You can't claim all cops are incompetent and then accuse them of running high-profile schemes to arrest innocent people and manage to keep it under wraps for decades lmfao. I'm not sure what that even has to do with police training. I'd advise that you stop reading sensationalist conspiracy theories because a hatred of police is going to do nothing but a disservice to you.
i'm saying police are unknowing pawns, if anything, in this scenario. they aren't trained well enough to say "hm... this test doesnt seem right... this
jolly rancher couldn't possibly be meth...". in fact i don't even think they're ALLOWED to question that. they're simply trained to arrest immediately once the test gives a positive, and the victim usually ends up taking a plea deal because they would only get in more trouble if they resisted. it's not a sensationalist conspiracy theory to acknowledge that officers are given inaccurate drug tests so that they arrest people, which gives the prisons and government more money. it's just something that objectively happens every day.
I still don't know what you expect to reform in police training. As a matter of fact I'm starting to believe that you don't really know what you're talking about. But by all means, I encourage you to walk down to your local PD and sit down with the chief, I'm sure he'd love to hear all your cool ideas of how we're going to make all cops not incompetent and prevent mistakes from ever happening again.
you would be right to say i don't have any solid ideas on how to improve the training, but i feel like most rational people would agree that whatever they're getting now isn't nearly enough. hopefully, after more attention is brought to the subject, police forces will actually be forced to do something about it.
and hey, maybe it isn't even the training. maybe they're just too lenient about who they let in, if there are so many cases of poor judgement similar to this one. perhaps some kind of judgement test, or stress testing would help.
