Surely there's a world where not every cop is bent on convicting the first guy that comes up in the conversation and every piece of evidence is seen as fake?
It's totally true that you can give cops ammo against yourself without realizing and you must be very careful wrt lying and saying the wrong things.
But there also has to be some kind of middle ground.
Cops don't decide who gets convicted. Your statements suggest that you are ignorant of the basics of the process you are criticizing.
Don't talk to the police under any circumstances. You cannot ever talk your way out of getting arrested.
There is no middle ground. Watch the "don't talk to police" video linked in the thread. He explains that it is like a ratchet: statements can only hurt, it is illegal under the rules of evidence for your statements to the police to be used to exonerate you!
