Still hard to decipher if that stuff about running away and up to 3 people shot at a “residence” answers what I said about shots from other residential places that go across the school lawn.
Maybe definition should be limited to someone with intent to kill people with a firearm at a school and discharges a weapon at the school.
“Mass public shootings” would also include places like shopping malls, churches, theaters, and bowling alleys, but typically exclude private residences which aren’t open to the general public.
