Gangs? Either mexican or white supremists. Graduated to rifles instead of pistols. Story says "assault" AR15 but who knows. Could have been Win 30-30s.

Way too bad a bystander was killed. Justice (whoever lost a family member will not have any) will be slow and ill applied. I wonder if these guys have any feeling for their own families? Maybe putting grandma, mom, and the kids all in the poor house too would make them think. Except that makes me just like Kim Jung Oon.
