There are lots of claims and counter claims being made here, even the irrelevent or debunked ones will no doubt be repeated again and again, louder and louder in an attempt to force them to be accepted as fact. Let's hope we can have some civilised discussion.
Personally, I think the African American community has been woefully let down by their "leaders" who appear like ambulance chasers saying the same old rhetoric but really perpetuating the situations that they make a good living from. They get on the news, promote their version of reality and tell the family of the deceased youth that they have been unfairly victimised and that the system is against them.
Lots of things were accomplished by the Civil Rights movement in the 60's most notably changing the laws to make discrimination illegal but these accomplishments have been squandered to a large degree. Community leaders should have been encouraging their youths to join the police and to report discrimination and harrassment - to amass a body of complaints that could not be ignored and take advantage of the laws to change the situations.
Instead, the rhetoric reenforces the notion that they should disengage from law-enforcement which results in mostly white people viewing law-enforcement as a worthy career. Policing a community should be done by people from the community - are african americans under-represented by the police in certain areas because of discrimination or because they simply don't apply to join? Complaining that the police are too white is misleading if that is the case. Complaints of discrimination would be more effective and could be used to effect change and make claims of discrimination carry more weight.
Of course, robbing a store should not carry a death penalty and I believe the use of language such as "executed in the street" is designed to mislead people into believing that this is the situation. The real issue is whether, after committing this violent crime, he then attacked a policeman in the same manner who felt the need to defend himself. Should the police have released the video of the robbery? Apparently yes - they were forced to because of freedom of information requests and the demands for transparency, not because of any attempt to ruin his character and besides, it is the act of robbing the store that does this, not the reporting of it.
The issue is really whether the police officer was attacked or not and if so, whether he overreacted and used excessive force in his self defence. There needs to be an investigation to gather the facts and if there is then sufficient evidence there should be an arrest and a prosecution. Demanding an immediate arrest is not and cannot be how the law operates and the community would be better served by leaders who educated people of this fact rather than riling up a crowd with emotive language claiming a miscarriage of justice before the justice system has operated. It does nothing to help see justice done either way because it ends up unfairly ruining the officers life even if they have done nothing wrong.
As an outsider it seems troubling that there are claims of so much harassment and discrimination but the poster-cases that get so much attention always seem to center on youth involved in committing crime and others, seemingly more worthy cases, get passed over by the leaders. Is it simply whether there is some involvement by a non-black person in the situation?
A lot has been made of the fact that the majority of black people are interested in this news story and white people mostly aren't as much. Crimes are committed to varying degrees by different ethnicities but how many see the need to protest when someone of the same color is killed? If some white kid robs a store, attacks a cop and get's shot in the process there are no protests - sure, people have the same color skin ... is that all that matters? Could focus on skin color alone be promoted too much within a community at the expense of other areas including criminality, behavior and personal responsibility?
Of course, I am not saying that racism does not happen but I don't think the current leadership is doing anything to truly solve the situation or improve things for their community. The message frequently being promoted that all problems are caused by racism and all white people are racist and benefit from white privilege does nothing to help outsiders want to engage in the issues. Without open and honest debate of the problems and the causes, not just the symptoms, I don't think America will be able to sort out it's race issues and unfortunately, this is unlikely to happen given the state of political debate right now.
Having personal cameras will probably shorten the media-cycle somewhat and provide important additional evidence in cases like this. I don't see anything else improving things for the forseable future.
