"and in at least one instance, a forged report was presented to a court as evidence" perjury is absolutely news.

The number of cops testifying on the stand who are never charged with perjury would likely astound you.

And the number of submitted police reports that clearly contradict reality.

There's a great netflix special about the drug lab in Massachussets. One lady was just straight up not testing samples at all, and marking them positive for the prosecution. Thousands were jailed this way. The chemist was only caught because her work was 4x as fast as her coworkers, so they investigated what was going on.

Now imagine how many smarter people than her just ran all the tests at normal speed, but faked the result. It'd be damn near impossible for them to get caught. I'd wager for every one caught, there are 10 that don't.

The distinction here is that this lie is so coercive that it's unethical to allow any confession or evidence following it.

What would you do if you don't have money for a lawyer, and the police say that your unassailable DNA evidence was found on a now-dead acquaintance of yours, and your options are confess to the murder and get 10 years with opportunity for parole, or fight and get life?

Even if you knew that the police can lie, know you are innocent but can't prove it, and you believe that the DNA test is real or the police are willing to fake it, you might confess b/c that's the best option.

Maybe not to you, but there are a lot of youth who never get filled in on that fact.

This might be true in the US but in some other countries the police aren't allowed to lie.

In some other countries the police are allowed to use physical force during interrogations. So what is your point?

Maybe the point is they don't need to be allowed that snd maybe they shouldn't be allowed that?

Then the user should say that and state their argument, no?

Which countries?

Canada: Yes

Australia: Yes

UK: looks like cant lie about evidence?

It's not allowed in the Netherlands and Belgium. I thought it also wasn't allowed in the other european countries but I'm not a 100% sure about that.

If the police are allowed to lie about evidence then this undermines the suspects chances for a fair trial (false confession). If the defense can show at a trial that the police lied during the interrogation, this would impact the chance for a conviction. At least this is how it works in the EU. In the US, I have the impression the judges don't take this into account.

That disparity may not be news, but perhaps it is worth discussing.

Lying to local (and state?) police is legal (I think). Lying to federal LEOs is a crime.
