Even just arresting them or bringing them in for assessment is enough to put someone in a dangerous position, because cops can effectively legally execute people. So the problem is any police interaction is potentially deadly and this is giving cops another arbitrary, potentially racist tool to interact with people who are just living their lives.
So we have 50 total out of thousands, if not millions of potentially negative police interactions.
You can't build a system of robots without some fault-tolerance. How are humans supposed to keep up to that?
Based on this data - how can you make the assumption that a police interaction is an inherent risk to life that is always unjustified?
We mostly pay police to show up and be generally aggravating to people who might be doing bad stuff - in some sense "being sketchy in the vicinity" is a valid reason for police action, which doesn't even always turn into an arrest, let alone a life-or-death situation. Those cases are the vast minority of police interactions total.
I only see 50 there. Are you sure you're looking at unarmed 2020 and not for all years?
I also just looked at a few unarmed shootings at random to get an idea of what they were like. Of the three I looked up I saw one guy who was shot while fighting with a police officer after being discovered at the scene of a burglary. One guy who was shot after a car chase when, after they had caught him, he got behind the wheel of a police car and the police shot him to prevent another chase. One guy, after stabbing someone to death and being approached by multiple police officers, faked a draw to "suicide by cop". My point is, I don't think it's even clear that all (or even most) of the 50 unarmed shootings are unjustified.
I had a dream a few months ago where I was standing in front of a computer. I typed in my name and got back a stream of video which showed every single moment of my life from multiple angles starting from the moment I was born. The footage came from a variety of sources, CCTV, smartphone cameras, dashcams. The system had videos of everything anyone had ever done. I didn't like it. Found it kind of disturbing.
Then basically you says its boil down to matter of subjective preference. So you don't like it, fine fair enough then don't be surprised that other people may like it.
I don't say that? You just have to think about how this stuff is going to be used in the real world where we actually live. The thing which is objectively disturbing is how easy it is to lose control of one's life once the government is able to record, observe and judge every single thing a person does. I believe such a level of transparency is only beneficial when it's applied to people who hold power over others; to subject everyone in a society to that kind of scrutiny would just be laying the foundations for abuse.
The problem is automated identification of faces. The solution is banning that.
