Or
Because it doesn’t happen that often
AND
Because the damn head of the department already resigned
BECAUSE
there is no justice when a black person is killed by the police. The prosecutor serves as the murderer’s attorney, the media finds the worst image and drags up every single thing that human being ever did wrong in their life as if it’s an excuse.
ALSO, MAYBE
White people aren’t mad about this enough to burn shit because it’s not a fucking baseball game:

Or a hockey game:

Or a football game:

Or a surfing competition:

Or because fucking pumpkins:

Damn black people riot when the state condones their family members’ and loved ones’ murder.
Clearly it’s them and not you (and your buddies pictured above) who have their priorities all fucked up.
GTFOH.
