My dude he served ten years when theres tons of people out there serving zero time, not even getting caught. You and every other angy poster in here can come back when theres another school shooting with double digit deaths, but we all know there will be crickets.
He should have only served enough time for an expedited legal execution by the state.
BTW, everyone cares about school shooting silly goose.
Caring don't mean taking guns.
Hope this helps.
