The prosecutor, whose task it was to present the case against Wilson had a weel-established pro-police bias. His father had been killed in the 60s by a black man and many members of his family were closely connected to the police.
The grand jury process is very simple. It is convened by the prosecutor to hear evidence presented to them by the same prosecutor, to determine if charges are to be laid. It is the responsible of the prosecutor to make the process as simple as possible but in this case, he overwhelmed the jury with the long and contradictory evidence presented. Rather than placing evidence before the grand jury to convince them to lay charges against Wilson, he went out of his way to show that Brown had caused his own death.
Nine of the twelve must agree before any charges can be laid and from the outset, given the composition of the grand jury and the bias of the prosecutor, it was clearly evident that no charges would be laid and thus it was.
When the announcement was finally made, the prosecutor spent a long time reading the evidence to the media, going into details of who said what and what contradictions there were in the evidence . especially of the black witnesses. He was clearly trying to justify the decision not to lay any charges against Wilson.
It was a travesty. The grand jury was loaded in favor of Wilson. The prosecutor was anti-black and pro-police. The evidence was presented in a manner to justify Wilson's shooting of Brown.
There is great anger and anguish in Ferguson. Some demonstrations broke out. There were also marches and some violence around the country.
Police violence against young black men continue. Police harassment/profiling against young black men continue.... Here is a recent example.... young black man was stopped and questioned in Michigan for walking with his hands in his pocket. It was 1 deg. C.
It is now up to the Justice Dept. to decide whether any action will be taken against Wilson for violating Brown's civil rights.
