I watched CNN and ABC News coverage of this event. Following this thread you don't get a sense of the outrage that exists over the shooting. Though these points are hotly debated here by a handful of posters, in the wider world there is a lot of concern over the following:
Brown was only eighteen. Six weeks ago he was still in high school. He had just graduated and was about to begin college. Brown was guilty of stealing a handful of cigars and bullying the shopkeeper. Many people don't consider that to be a violent felony or Brown to be a violent felon. Many people consider that stealing a handful of cigars and acting like a jerk. He got into an altercation with an officer. The details remain unclear. Despite being unarmed Brown was shot six times. Many people feel there should have been a way a trained and experienced police officer could've subdued him short of shooting him six times and killing him.
African Americans have a long history of being discriminated against and being subject to police violence. Many people feel he wouldn't have been shot six times and killed if he hadn't been black.
There are many valid complaints on the actions of this police force, and of the treatment (past and present) of black people by many institutions in the US.
That doesn't make all the complaints valid, and invalid complaints should not be given deference because of other similar valid complaints. That Brown was unarmed is a nonsense complaint. One does not need to be armed to be a threat to life and limb. Many people think that is the case, but many people don't understand how fragile and resilient life is at the same time. The officer was already injured. He was injured by an unarmed man. There isn't a dispute there. I'm not going to make too much of Brown's physical size and strength because that's often overplayed. You don't have to be bigger and stronger to be a threat to someone's life and limb, and this is especially true if there was already a struggle for a gun. Yes, weapons are very effective at increasing the ability to kill and injure. For some odd reason people take this to mean that the lack of a weapon means 'safe' or a low ability to kill and injure. This simply isn't true. Similarly, people feeling that there should have been a way for the officer to subdue Brown without killing him doesn't mean that there was one, or even that there could have been one. At the point there was a struggle for the actual gun, switching to a Taser (if there was one) would have only been advisable if the firearm was actually lost. This is even without the injuries the officer had already sustained. There simply isn't time to switch safely during such an altercation without backup there to engage while the other switches.
Brown committed a violent felony. It's admitted by all the relevant parties and well evidenced on video. That some people don't consider him a violent felon isn't relevant to anything. Objecting to what his actions show and what is an accurate label would be like objecting to calling him a teenager, wouldn't it? It's kind of like the joke, "You have sex with women all your life, but you have sex with
one goat and all of a sudden you're a goat-******." Yes, you commit one violent felony and you're a violent felon. You have an age that ends in 'teen' and you're a 'teenager'.
This is all from the 'us-versus-them' mentality where all the criticisms against one's own 'side' are viewed as invalid and against 'the other' side are valid. Even if one must take a side, that doesn't mean everything thrown at the other side has sound basis.
