Nice find Qwepir.
police are held to a higher standard because police have internal affairs, a code of conduct, and an organized bureaucracy and ranking system that gives them a level of control and oversight over it's own members that protests do not have.
All things I have told you before. You should also remember that I told you that the police don't go around looking for action. They don't shoot people to push some agenda to kill minorities, they don't shoot because they are bored, they don't shoot people because they are lazy, they shoot people because the situation called for.
Tasers don't work 100% of the time, neither does pepper, batons break bones and leave bruises. You want to approach a guy who has knife with a baton or a can of spray? How about an Axe?

Also just because you hand cuff someones hands doesn't stop them from kicking you are moving uncontrollably in the back of the car. Some times you have to cuff them in a way so that they are almost in a ball. This is reserved for those refusing to comply. However said move could affect the diaphragm which leads to suffocation. From what I heard Gray died in custody while in transport possibly a damaged larynx. Choke holds are down to knock out people who are difficult to restrain, here the officer probably performed it incorrectly. However this is speculation and shouldn't be taken as fact.
Their might be tribal cops, but all races have their tribals. There are tribal blacks, there are tribal Asians, there are tribal Hispanics, everybody. There are also police officers of color, holding white officers accountable based on speculation while looking away from everyone is a disgusting double standard.

Like this disgusting piece of stuff.
