you cant have firearms in bars in California....

you also cant carry firearms in California while masked to conceal your identity....

high capacity magazines (over 10 rounds) are illegal in California, unless grandfathered in, which is impossible for him to have obtained legally...

now, for the stuff that really matters...

he was a Marine, and machine gunner, which likely means a SAW gunner or door gunner for a chopper...

he either rode around cutting people in half with the SAW, or blowing people apart with a .50 cal out of a helicopter....

imagine what that would do to your mental stability...

he also knew people that went to that bar, because they made fun of him constantly for having a lazy eye...

so you have a guy, that was made fun of all his life, joined the Marines, blew peoples body parts off, came home, got no help, and snapped....

maybe people should check how they treat people, instead of trying to screw other people over, because thats where you get into these situations in the first place...

by people screwing other people over.....
