Geniuses

Pauline Wolak asks about Navy Yard shooter Aaron Alexis,

What the hell did anyone do to stop this jerk from ruining the lives of innocent people again and again?

Two incidents with guns and treatment for serious mental illness tell me this guy was a walking time bomb. How the hell did those closest to him not see it?

When he shot out the tires of a car owned by men he felt “disrespected him”, were you surprised? When he shot into the ceiling of his apartment because his upstairs neighbor was too loud for his taste, were you shocked? When he was booted from the Navy for a “history of misconduct”, were you confused? Were you completely unaware of his arrest record?

About as unaware as the geniuses that gave this guy a government security clearance, apparently.
