well my dad has been a cop for 16 years and he deals with child molester, murderers, and straight up dumb shits. They have to use some sort of force to restrict people cause they don`t want other people to get hurt. people blame the cops for putting a stop to people doing dumb shit and when they finally do something that causes a cop to use some sort of force they get all mad because they think its wrong but it isn't. Those kids wouldn't haven't been shot if they were in the crowd. like where are their parents? ya i think Obama really doesn't do anything but police officers have to use aggressive force like rubber bullets and sand bangs and pepper spray and even tazers. Like that dude that kept getting punched the cop was in the right cause they dude was resisting arrest which gave the cop a right for him not to resist. Don`t be upset with consequences for your actions and yes some cops do think they are in total power and are asshole but the cops always look bad when they have to secure a situation cause people refuse to listen and yadah yadah. Welp fine they shoot rubber bullets and guess what the people leave and the situation is over. So ya here and there cops do use excessive force like when my dad arrests child molester he lets out his anger and giving him a couple of "Do-nots" ( punches ). Over all Obama cant really control every single town police department. People shouldn't get upset when cops have to use some sort of force to keep people to continue from doing dumb shit.
