Tragic that the latest big brain idea has moved on from more guns is the solution to LESS DOORS !!
(not that the Doors and Windows lobby would allow that)
they've really thought through those ideas.
1 armed resource on the only door in or out.
The attacker still has the element of surprise and immediately takes out the "resource" and now has full control over the only exit to a building full of kids and teachers - jesus wept.
nothing will ever change with guns in America sadly. People so entrenched that theres no body count that would change there minds.
