Re: Surely though
"To reduce the number of false positives you would inherently increase the number of false negatives."
That's BS if the actual recognition works. And it's obvious it doesn't. Fix that first and after that start to use it to arrest totally innocent people.
Because it's obvious this piece of crap is used to arrest anyone claiming 'software flagged him/her'. How convinient, isn't it?
90% false positives is sure sign of it, no-one in Police cares about false negatives: That's not the reason this system is in actual use.
