Also, their whole job is dealing with people who constantly lie to them.
What you're stating is your wishful thinking. Don't get me wrong. I'd also like what you say to be true. It very much is not. Quite the opposite, which is why salespeople "work".
The amount of AI bullshit Senior+ level developers just paste to me as truth is astonishing.
Police get raises and recognition for closing cases. In general they don't care if you're guilty or not, that's someone else's problem. Same with the detective, same with the DA. The more cases they close they 'tougher they are on crime'.
The next thing occurring is

* Nobody can find a police department that administers any kind of general cognitive test.
* There are large states with statewide written police aptitude tests that are imperfect but correlated to general cognitive ability, and maximizing scores on that test is the universal correct strategy.
* It's a luridly stupid policy and most municipalities aren't luridly stupid.
I think this happened like, once or twice, in one or two of the 20,000 police departments across the United States, many of which are like one goober and his sidekick (no offense to them; just, you live in gooberville, you're a goober), and now it's an Internet meme that police departments specifically hire for midwittery. Nah.
The LST isn't; it's a domain-specific occupational exam.
If you find a place that (1) uses the Wonderlic and (2) has recently (like, not all the way back in 2000) claimed there was a high-end cut-off for applicants, you'll have disproven my claim. I don't think giving general cognitive tests to prospective police officers is common; this is why there are things like the LST, the PELLETB, and the POST.
The issue is that facial recognition is just not very reliable. Not for humans and not for machines. If you look at millions of people, some of them just look incredibly similar. Yet police apparently thought that was all the evidence they will ever need. A case so watertight there's no point in even talking to the suspect
To define the line between the two, calculate the percentage of cases when mainstream CPUs return anything but integer 4 after addition of integer 2 and integer 2, and use that as the threshold to define "reliable".
