I would have called 911 immediately.
if you lived in Aztlan Nuevo like we do you'd realize the police are no use.
Cops can't arrest 60% of the town.
here in the occupied territories the Mexicans start shooting round 11:30 and go for an hour or so. Cinco de Mayo parties, 4th of July (irony?), Halloween/ Day of the Dead and Mexican Independence Day same thing.
They just love to shoot guns in the air and there is not a damn thing you, I, or the police can ever do about it.
