There are lots of things that are protected activities that I would like surveiled. Militias. The KKK. Neo-nazis. I certainly hope the FBI and other law enforcement agencies are keeping tabs on their activities.

I would agree, with the giant caveat that I would like those activities to be surveilled only upon a showing of probable cause and with judicial oversight. The government shouldn’t have carte blanche to “investigate” citizens who are not suspected of committing a crime.

In Western jurisdictions, probable cause and judicial oversight are only relevant to searches of private property, arrests/etc. Police have always been empowered to surveil public behaviour, and in my opinion, rightly so.

It would be incredibly impractical to require judicial authorization for something as simple as browsing a public neo-nazi forum, or driving around looking at known drug-spots.

The question is whether the ubiquity of social media/phone cameras has changed our attitude. Arguably, we've created an inescapable, 24/7 surveillance apparatus . If you attend a protest, there's a real chance your photo may very well end up on Twitter/Facebook/etc, inadvertently or otherwise.

I do think it's time to discuss the role of phone cameras in modern society.

Re:Police surveilled protests with help from Twitter-affilia... by darawk on Thursday July 09, 2020 @08:28PM (#23786852)
I agree in spirit here, but in practice in order to get probable cause of criminality or criminal intent, you need to do a little bit of surveillance/monitoring first. And it seems to me that a good compromise is "monitor publicly available media, like twitter to look for evidence of criminal intent, and then use more invasive tactics if you find it".
Re:Police surveilled protests with help from Twitter-affilia... by d2v on Thursday July 09, 2020 @09:34PM (#23787252)
It takes a lot of faith in law enforcement to believe they won't abuse that power, especially given they are the target of criticism by these protests. The argument that it is illegal for them to abuse / misuse this information isn't very compelling either, given that they are the ones responsible for enforcing the laws that they would be breaking. I might be okay with this info just ending up in the hands of the FBI, but I definitely wouldn't want it winding up in the hands of my local law enforcement agencies, who are known for harassing and intimidating critics.
Re:Police surveilled protests with help from Twitter-affilia... by darawk on Thursday July 09, 2020 @10:08PM (#23787439)
It's not that I think they won't abuse it. I know that they'll abuse it. The question we have to ask is whether their abuses will be worse than the consequences of total inaction on their part. And I think that balances in favor of surveillance, when it comes to public social media data, but certainly reasonable people can disagree.

who are not suspected of committing a crime.

How about people suspected of planning a crime?

It would be really hard for cops to prevent crimes if they had to wait until after it was committed in order to surveil.

Re:Police surveilled protests with help from Twitter-affilia... by ponker on Friday July 10, 2020 @01:41AM (#23788510)
In general, cops directly prevent almost no crimes. Their job is basically to respond to crimes and either stop it in progress or find and punish the perpetrators. If they have a prevention effect it is from deterrence.
Re:Police surveilled protests with help from Twitter-affilia... by refurb on Friday July 10, 2020 @11:07PM (#23799125)
How many beat cops do you think have been patrolling at night and come across some shady character casing the neighborhood? I'd bet every single one except for maybe the cops in Malibu.

Regardless, there are cops whose jobs are to identify people who may be planning a crime. So my question stands - any concerns with surveilling those people?

Re:Police surveilled protests with help from Twitter-affilia... by dfxm12 on Friday July 10, 2020 @11:49AM (#23792762)
Cops are certainly aware of white supremacist activities, but they don't need to surveil anyone:

In the 2006 bulletin, the FBI detailed the threat of white nationalists and skinheads infiltrating police in order to disrupt investigations against fellow members and recruit other supremacists.

https://www.pbs.org/newshour/nation/fbi-white-supremacists-i...

Also, let's not forget the KKK's history of organized crime. They've earned any surveillance they're under. It's far from a straight comparison between them and ad hoc protesters when you're talking about "protected activities".

Re:Police surveilled protests with help from Twitter-affilia... by seph-reed on Thursday July 09, 2020 @08:08PM (#23786740)
Easily. Without hesitation, obviously, hard yes. If the KKK wants to be a tiny minority of people who lack the nuance to direct their anger at anything other than a color of skin, maybe we need to work on our education system. If they haven't committed a crime, then either they haven't hurt anybody, or we need to work on our judicial system.

Inevitably, the microscopic amount of good that could be done would be vastly outweighed by the chilling effect on every group that was trying to create positive change at the expense of the oligarchy. Aka: true patriots.

The government shouldn't put someone under (specific|personal) surveillance without strong evidence of course. But I don't see what prevents them from reading twitter, going into public chat rooms, etc.

I think that was the general idea, yes. Or at least, before they have strong indication that it’s likely to commit a crime.
Re:Police surveilled protests with help from Twitter-affilia... by darawk on Thursday July 09, 2020 @08:19PM (#23786810)
How should they determine when a group is about to commit a crime though? Usually that's done via pre-emptive surveillance. If they are not allowed to surveil groups that they merely suspect might one day commit crimes, it will be very hard for them to know anything about their activities before the crimes actually get committed.

It's certainly possible that this is just the price of freedom. But I think its a rather heavy price.

Re:Police surveilled protests with help from Twitter-affilia... by minerjoe on Thursday July 09, 2020 @09:58PM (#23787386)
"Usually". Evidence? I doubt that the police pre-emptively stop many crimes at all. They catch criminals _after_ they have committed crimes.

Even if they were able to catch every crime before it started, ala minority report, they, based on past behavior, would most likely seriously abuse that power hence the strong opposition here to having them even come close to posessing that power.

Here's a long list of terrorist incidents, some of which were pre-emptively disrupted by the FBI:

I don't really understand your point. I'm not arguing that they won't abuse their power. They will. They always do. The question is whether or not the abuses that might occur as the result of analyzing publicly available information are worse than the harms that might come from not doing so. I come down pretty squarely on the harms from not doing so being greater, but reasonable people can disagree, I suppose.

Re:Police surveilled protests with help from Twitter-affilia... by minerjoe on Friday July 10, 2020 @10:51AM (#23792032)

Says the FBI, with a conflict of interest large enought to drive a big truck full of fertilizer though in publishing these things. They also have a varified history of lying through their teeth.

You gave me a press release from an organizaion that has a history of being deceptive. Why would I, or anybody, take it as a "concrete list?"

The thread of discussion here is that the FBI needs to have broad survaillance capabilities to catch crime before it occurs. The list you gave has verly little support for that in that almost all of the acts in the list were not stopped due to any survaillance, but rather invesigations after the fact. You could assert that they might have been stopped, but that is conjecture.

How many criminals announce their plans on Twitter in a way that law enforcement can use to prevent a crime? From my perspective, it seems like the potential for crime prevention is small compared to the potential for abuse.

Re:Police surveilled protests with help from Twitter-affilia... by darawk on Friday July 10, 2020 @01:36PM (#23794063)

And this feeling you have may stem from another political narrative being created and amplified: the fear of 'the other'. The fear that justifies all of this to so many people.

Sowing the FUD that e.g. most people from Mexico are "criminials, rapists, carrying disease", or that Moslims are terrorists. That terrorist sleeper cells may be everywhere. A gliding scale of xenophobia created for political purposes.

There is an ocean of options in between “do nothing” and “surveil and database every citizen who potentially maybe, might, could exercise their constitutional protections and protest.” A vast amount of options.

Re:Police surveilled protests with help from Twitter-affilia... by darawk on Friday July 10, 2020 @02:14AM (#23788679)
Let's keep in mind what we're actually discussing here. We're talking about police monitoring public Twitter feeds. They're not tapping phones. They're not secretly infiltrating groups with undercover agents. Just reading stuff that's published in public, for all the world to see.

Reading public messages seems like a super reasonable thing for the police to be doing, to keep tabs on groups that have recently engaged in disruption and violence. Whether those groups are right wing or left wing.

Re:Police surveilled protests with help from Twitter-affilia... by pnako on Friday July 10, 2020 @04:50AM (#23789485)
It's hard to disagree with this point, really.

I don't see how you can prevent the police from reading stuff that's being broadcast for everyone else to see.

And threats of violence, or evidence of organizing to cause violence, should be investigated.

Re:Police surveilled protests with help from Twitter-affilia... by Proziam on Friday July 10, 2020 @08:56AM (#23790992)
I think it's rather easy actually.

The police aggregate vast sums of data and uses it in ways that the public does not understand, intend, or expect. It's not unlike the way people 'sign' away their privacy on the internet without being aware that their data will then be sold and resold and used against them.

It is a common belief that information is a weapon, and it certainly can be used as one. So does it makes sense, at least from one perspective, that our information should not be legal to catalogue? After all, it is illegal in the U.S. for the government to create a registry of firearms owners because such a registry could be used against the people and its very existence would be an infringement on the rights of those people.

Re:Police surveilled protests with help from Twitter-affilia... by darawk on Friday July 10, 2020 @01:38PM (#23794095)
But this information is already being cataloged. It's being published on a platform that explicitly catalogs it, for the public. Anyone tweeting on Twitter is doing so with the full knowledge that anything they say might get signal-boosted by someone with a high follower count and become a major public incident. It happens with extreme regularity. The idea that there is some kind of expectation of privacy here seems far-fetched to me.
Re:Police surveilled protests with help from Twitter-affilia... by Proziam on Friday July 10, 2020 @03:54PM (#23795653)
We as a collective seem to treat the government as a natural person online, but not in person.

If a police officer sits down at the dinner table next to me and listens in on my conversation with friends and family, I'd be quite uncomfortable. I'd feel equally uncomfortable if they sat across the restaurant and pointed a microphone at the table to record everything. However, suddenly we treat them like normal people if they download the entire contents of our digital lives and process every word we've ever written online.

It's one thing for Twitter to be accessible to natural persons publicly. It's another for a government to treat everyone as though they are under investigation at all times, without a warrant.

For clarity, in my opinion, a police officer who just happens to follow me on twitter because he likes video games is a natural person. However, he stops being a natural person once he starts representing the organization he works for.

Re:Police surveilled protests with help from Twitter-affilia... by darawk on Monday July 13, 2020 @03:26AM (#23818014)
Twitter is not a dinner table though. Twitter is a public square. I think you could make a reasonable case for Facebook being dinner-table like. But Twitter has privacy settings. You can protect your tweets if you want to. If the police were breaking into protected accounts, I would agree with you. But Twitter seems about as public as it gets.
Re:Police surveilled protests with help from Twitter-affilia... by Proziam on Monday July 13, 2020 @08:25AM (#23819979)
Imagine every person in a public square has a police officer following closely behind them with a microphone in one hand a video camera in the other. And we're not even touching on the 3-letter-agency relationships with tech companies which almost assuredly gives them access, even to 'private' profiles.

Innocent people should not be surveilled ruthlessly on the off chance that every now and again we catch one evil person. In my mind, it's like the TSA invading everyone's privacy without ever catching a single terrorist. It's a waste of resources, on top of being a disgusting behavior.

Re:Police surveilled protests with help from Twitter-affilia... by darawk on Monday July 13, 2020 @02:10PM (#23823725)
The difference is that in a physical public square, you have a built-in expectation of ephemerality. Everyone expects that their behavior in some random physical space is not going to persist forever. Twitter, on the other hand, is explicitly build with the expectation of what you tweet persisting forever.

On the other hand, there are tons of cameras in public spaces too. So, even though people have had a built-in expectation of ephemerality, that's already been violated for quite a while now.

Re:Police surveilled protests with help from Twitter-affilia... by Proziam on Monday July 13, 2020 @03:52PM (#23824895)
I don't expect Twitter to last forever either. Myspace sure didn't.

That said, in my view, surveillance against the average person has got to go.

Yes. That's better than the alternative. So many things can be construed as criminal that I don't think it's an impediment to the investigation of actual criminal in practice. If anything stops police from wasting our money surviving groups that are not actually threats to anything but the government wants under surveillance for political/ideological reasons.

Re:Police surveilled protests with help from Twitter-affilia... by tharne on Friday July 10, 2020 @12:20PM (#23793094)
That's a nice ideal, but ultimately very naive. Your idea would work great until a neo nazi group or a terrorist organization executed an attack killing a large number of people. Then everyone would be screaming at the government demanding to know why they weren't monitoring more so they could prevent just such an occurrence.

Sure. But a lack of concrete, precise information doesn't mean we can throw up our hands and just call them equivalent, either. The FBI disrupts quite a bit of terror activity, and quite a bit more never materializes because the FBI exists. They've certainly engaged in their fair share of abuses over the years, but I don't think you can seriously argue we'd be better off without them.

The last few cases that come to mind (Breivik, Tarrant) are from lone wolves that had radical ideas but were not affiliated with any group.

It must be very difficult to catch (unless you want a surveillance society where everyone is suspect).

Even in cases where it's planned and announced it's difficult to stop (Al Qaeda did announce they would assassinate Charb, editor in chief of Charlie Hebdo, and despite police protection they managed to do so).

This part of your comment really, really rubs me the wrong way. Your personal inclinations absolutely cannot direct the apparatus of state on a whim. Either those groups are suspected of criminal activity or conspiracy to commit criminal activity, which is probable cause for surveillance, or they aren't.

Yes! You either believe in free speech and freedom of assembly or you don't. If these groups are a clear and present danger, show probable cause already. If they aren't, counter-protest, shame them, embarrass them, whatever.

More often than not, hate groups can't help but cross that line to violence or are already linked to violence. It's really almost an oxymoron to talk about neo-Nazi groups that "eschew violence" since they almost always believe in genocide and the violent overthrow of the government and are working towards it. I know it's a tempting rhetorical device, but it's really a strawman.
