I've been reading about an awful lot of incidents similar to this lately, people who just flew off the chain and killed people over little shit, like just recently in Georgia four were shot, including the gunman, and one store clerk died because a customer was asked to put on a fucking mask, there was the road rage incident in California where a 5-6 year old boy was shot and died in the backseat of a car, there's more, but listing all of them would be draining, there was the religious guy in Georgia who went through shooting up Asian massage parlors in Georgia because of his "sex addiction"...
Maybe I'm late to the party but it would seem we need to rethink a few things about the right to bear arms.
