They don’t like authority at all.
Zimmerman represents all the neighborhood watch captains across the country. All the people who might watch them as they skulk around at night and take what they want. In that respect Zimmerman might as well have been a cop. He’s on the side of property rights and they are on the side of piracy.
The Zimmerman trial was about their right to beat the crap out of anyone who watches them. And they lost, and now they intend to take it out on anyone and everyone especially police.
Yes, but to actually DO anything they'd have to put their welfare sucking a$$es at risk. They could get Treyvoned. Safer to demonstrate then go home and celebrate with beer and blow paid for by the taxpayers.
