Here's one small, disgusting detail from the aftermath of one of the most horrific incidents of government-instigated urban violence in modern American history:
In May 1985, a little African-American boy runs from a building in flames in Philadelphia. The fire was started by city officials, who literally bombed their own citizens, triggering a conflagration that would kill 11 people and destroy 61 houses. A white cop runs out and rescues the kid, who is covered in severe burns but survives.
Following the disaster, the rescuing officer returns to his police station to find the words "Nigger Lover" scrawled on his locker door.
Those sorts of mind-searing embers...
