The only problem with not resisting arrest and giving the cops a reason to mess you up is that well...f*ck it they'll do that anyway.
Just recently a legally blind man "fit the description" of a suspect. The cops stopped him, he did everything they said despite not being able to see them. Then they slam him to the ground.
Of course there's the guy who got shot for following the officer's orders and trying to get his idea.
Etc...
It doesn't matter what you do anymore. If you find the wrong cop it's just a matter of how it happens, not whether it'll happen or not.
