"Joker" is from the new Batman movie where the "Joker" kills hundreds with his assault weapon.
This "real Joker's' T-Shirt reads, "Guns don't kill people, I do".
He got pissed at his boss, and sent email to a former coworker threatening to shoot his former boss and some former coworkers.
This nutcase had an apartment full of assault weapons and ammo, but cannot be charged with a crime since he has committed none yet.
Once he kills 35 people, the cops can get him, though.
He is now just exercising his 2nd Am rights.
How does someone afford 8 assault rifles and hundreds of rounds of large caliber ammo? Hell, I used to like firing my .39spl revolver, but the ammo costs for .38spl's made very much practice too costly except with little, .38 target rounds
