@chappy58; everyone at that school is a VICTIM of US Gun Policy that allows anyone aged over 18 to have unrestricted access to high powered, military grade firearms without having had any background checks of any kind.
And yet that rotten $#%^&* Trump immediately went public while people were absolutely distressed by the slaughter of innocents and said that having the right carry such weapons is great as long as they don't bring them to his meetings.
People make mistakes such as failing to lock a door all the time, that doesn't make it OK for America's great big brave mass slaughtering male mongrels to mercilessly slaughter little kids and their teachers!
