The door release is only one push button away.
I love the dumb asses who are pushed/told to get back who then crowd in again when the handler is trying to get control of his K9 and make it release.
The dog gets in an agitated state and views those people pushing in as a threat. He's not going to let go of that chew toy for nothin'
