This incident is reminiscent of a show that featured videos of inept criminals. On one, a robber entered a bank through double glass doors and stuck up the teller, then went to leave. He attempted to leave through the door by pushing it but found it wouldn't open. Thinking that the tellers had tripped a switch to lock the doors, he frantically began to throw himself into the door. Finally after several bashes the door gave way and he ran off. As it turned out all he needed to do was pull the door to open it.
This is my opinion, and change is good.
