2. Juries believe them by default.

There are many contexts where juries will believe one party prejudicially over another, and/or one party has some form of extraordinary power in defiance of facts or objective reality. (What these are, and their directions vary over time.) Up until now, it seems that our only and very crude solution has been to introduce a "correcting bias" in the direction deemed most likely to increase the amount of justice enacted in society.

It seems to me that gathering more information in a more timely fashion and making objective and contextually relevant determinations is the rational and technically savvy direction to go. However, I'm not so sure that human beings are mature enough as a species to actually apply such informational power in a truly fair and rational manner. I rather think that we'd be prone to using such power to bolster the whims and prejudices of the status quo, at least in the short term.

Now that is an interesting question. Lowering the time discounting of an entire society is pretty much awesome for everyone involved.

We need to get some RCTs or at least large epidemiological surveys on the time discounting of sousveillers & lifeloggers.

I'm inclined to believe that I don't want surrogate memory. You might be interested in an episode of Black Mirror, "The Entire History of You", that is premised around this.

If not, what makes you think that the current spot on the continuum from "accurate/prosthetic memories" to "inaccurate/solely internal memories" is the best spot?

Or, an even more likely occurrence: Police get dispatched to domestic disputes quite frequently, where there's lots of hateful argument going on. The content of these arguments is often something that you don't want your neighbours or colleagues finding out, for a host of reasons.

Upside, most especially if you are black: the police do not smash your door down in full riot gear, shoot your dog, point rifles at your kids, put a gun to your head and threaten to arrest you on a trumped up assault charge. All because they got the wrong address.

There is no "right" decision.

I personally fear the legal system much more. Both because it is more likely and it's consequences are more severe. Being ostracized and fired from my job cause I'm a furry vs spending anytime in jail/prison (which would probably get me ostracized and fired anyways).

Or the risk of what the police might do if unrecorded outweighs the neighbours gossiping.

Also in suburbia it is my experience that neighbours can hear what is being sad in a domestic anyway. Drywall doesn't muffle yelling much.
