Have you noticed "Wilding" in your neighbourhood? Massive shoplifting, muggings, home invasions and theft like?

The local news just showed video of a bunch of black kids storming a store and stealing anything they could carry, but the "news" readers didn't dare point out the obvious and say they were all black. God forbid they would report real news that might help catch criminals. That would be rude!
