Why is the world full of idiots?

I find it annoying how so many people act idiotic. A white dude gets arrested for assault and was tased. So how come the black guy gets tased for attacking an officer in the same way and for dome reason it's police brutality and racist? But it's not just getting arrested. Remember the Kmart card that had to be taken down because it said black holes in it? That was because some group decided everyone hates them so it obviously must be a verbal attack referencing black women to w****s. I'm sure you remember the officer who punched a teen in the face because she grabbed the officer and pushed him away. So now a police officer can't use self defense to protect himself and others in classifiable battery or to use the quickest and easiest way to stop assault, obstruction of justice, and a possible attempt at escape? Now remember this has nothing to do with race. Why does everyone jump to say it's police brutality? The girl probably just got s nasty bruise. I don't know this for sure but that seems to be the worst that might have happened. This also cause huge flame wars over people saying officer abuse power and do whatever they want to inflict pain. which isn't true in any way. Sure maybe a couple idiot accidentally made it through but that dosent mean all of them just want to hurt you. I bet the people saying this have an experience close to what you see idiots do on cops. These might not be awesome examples and I might have communicated the wrong message. I'm not racist. I'm not trying to stereotype any one. I just feel it's ridiculous that people jump to conclusions without imagining every possibility. Put your self in the officers shoes. Your trying to arrest one person in an escalating "temper tantrum" in a crowd of people you don't know. Any one of them could try to help there BFF and hurt you or others. Your grabbed and thrown back by some you don't know who is yelling. What's your first instinct? Protect yourself. Please post your opinions on my rant.
