As much as I don't like single big entities having this power, this seems like a ridiculous stance.
So I can have two pictures and look at them by hand, and use my own brain to categorize them. But the minute I use a computer to do so I have committed a crime.
It's this kind of stance which is going to make machine learning algorithms that casually identify people for convenience sake illegal. What the people in the court system have decided, is that they are frightened of being found out as hypocrites - as people who take bribes, and people who do bad things in public.
You can always do bad things in private. No one can stop you from doing such things, especially when they come short of murder.
There is essentially no difference between this technology, and the technology used for license plate recognition, but license plate recognition is totally legal.
In many places, if you were pulled over by a cop, you would pay a hefty fine, and the automated license place readers will simply fine you a bit less or let you go to court. What's wrong with recognizing people that are committing crimes and sending them a notice, "We were about 1% sure this was you doing something wrong, so here's a 1% fine." Everyone agrees such systems will be initially imperfect, but everyone is also totally agreed that present law enforcement is imperfect. I fail to understand the problem.
Unless of course, the problem is that everything is really run by criminals, and we're getting way too close to knowing the truth. That could be a problem.
Edit: I appreciate honest debate more than downvotes. If I have a shitty idea, please tell me why. Unless of course, you are afraid of honest discussion. Cowardice is always acceptable here.
