False positives vs false negatives. Most crimes are committed by young men, but most young men aren’t criminals. Same thing happened with medical tests for rare conditions — if you have rates of 5% false positive (0% false negative) and 1% criminality rate, then ~84% of those you shake up are innocent.
Scooter crime seems to be committed by men under 30, are you talking age-related profiling? So shake-down a couple of million people and you will probably find the evidence you want?
How is attacking the demographics of crime working for America, and the other countries that do that? As far as I understand, the efficacy of profiling is extremely poor
Thankfully, racial-profiling is against the law in the US. Unfortunately, some involved in law enforcement do it anyway (sometimes unintentionally), and when they are caught they are disciplined.
Under Trump and Attorney General Sessions, the Department of Justice said they were shutting down investigations of police departments for civil rights issues. (I don't remember the exact details.)
It's cheap and efficient to wear a mask, where it is the taxpayer's money being wasted on facial recognition systems, and on top of that: cameras don't prevent, and are not even being used to prosecute criminals, there are not enough resources to do that, as someone else already pointed it out:
> You only have to look at the widespread increase in CCTV use in Britain. Now when you get mugged in London the police can get you a little video of your hooded attackers for posterity. Except they only have time to go through the recordings if you got murdered, otherwise you will just get a crime number.
But hey, have fun with illusion of safety, deprived freedom and a complete waste of money.
