They want other peoples money and white peoples blood - right or wrong is not in play
They wanted the same thing in the Zimmerman incident, but made some mistakes and it did not quite work out. In the Ferguson incident, with the help of the Ferguson Police Department early on, they corrected those mistakes.
The Ferguson Police Department aided them greatly by not nipping the rioting, burning, and stealing in the bud and dispelling the rumors. Instead of doing that, they sat on their toys, menacing and probably taunting the peaceable protesters and allowing the rumors to spread and fester uncontested. Another mistake, in my opinion they made was allowing the outside professional agitators to set up camp. The Mayor, City Council, or Police Chief should have immediately asked for a Declaration of Martial Law and employed police dogs, water cannons or fire trucks with water hoses do disperse the burners and stealers. The outside agitators should have been attested for inciting a riot instead of being patted on the back and given the keys to the City.
