Shooter incident at elementary school in Uvalde, Texas - 19 children and 2 adults dead

Blow the door off the hinges with a shotgun . . .
Can't say I've ever tried that, do you need to shoot the deadbolt too? Otherwise seems like you're going to be doing a lot of kicking, assuming the doors swing into the room. Or does the door just slide out after the hinges are blown off (assuming deadbolt has some wiggle)?
