Not So Smooth Criminal
My father was a lawyer. When he was a federal prosecutor, they had a case where the defendants were holding up a bank. They successfully held it up and were headed on their way out. Then it all went wrong for one simple reason. The door would not open. They repeatedly tried pushing the door and slamming into it but eventually gave up.
In their panic, they thought they had been locked inside the bank by the manager. The authorities showed up, calmly entered the bank, and took the puzzled bank thieves into custody. The door was a pull door.
