White shooter, black victim, history of threats, no action taken (because white kids aren't taken seriously as threats) AR-15.
It's almost like a standard profile, except that the shooter is a couple of years younger.
That just shows that the toxicity is creeping lower and lower. Maybe it'll be a 12-year-old or a 10-year-old next time. As long as they're big enough to hold the gun and pull the trigger.
