Don't let yourself be discouraged by Police Misconduct. If you're rights have been violated, REPORT IT. You can file an official complaint. Sure, maybe nothing will happen right away, but one day that piece of shit is going to abuse someone else's rights in a BIG way, like beating the shit out of some poor kid, and then that cop is going to be reprimanded pending an investigation, and when the lawyers start looking through any previous reports of this behavior from this cop, they'll find not only YOUR complaint, but probably a shit load of others as well. MORE than enough for a Lawyer to build a solid case against them.
That is why it is so important to SPEAK UP and flex your rights. Don't just give up on trying to protect yourself. You're stronger than that.
