This is part of the "transformation" the president speaks about. The American people elected a radical "community organizer" as president. Then they reelected him. He has appointed like minded people to every seat in government. Those he couldn't appoint, like Sharpton, are employed in an advisory capacity. Sharpton's recompense is no IRS goons on his back.
In the olden days, pre 1970, "community organizers" used to be called rabble rousers. Their "job" was to rouse the rabble. Society then had little time or money for such foolishness. Now rabble rousing is a respected career choice. One you can ride all the way to the White House.
The next two years are going to be hard. Obama wants Americans to suffer and he is rousing the rabble to apply the suffering. He is running out of time so look for him to step up the game.
Holder, Sharpton, deBlasio, et. al. have declared open season on police. The police and the rabble understand this. The next move is up to the individual police departments. Will they simply withdraw from some neighborhoods as they do in Europe? Or, will they fight back against the rabble, the chaos, and the full weight of the US federal DOJ? Your statement suggests the latter. I think they will withdraw and practice their trade in areas that appreciate law and order enough not to assassinate police officers.
Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
