screen check 

A "Screen Check" or "Screen Checking" is when a cop in a patrol vehicle brake checks when a suspect is handcuffed in the backseat. Due to the suspect being handcuffed, and hands not free to block, the suspects face will smash into the metal screen divider of the patrol car. This will cause cutting and bruising and sometimes a broken nose.

"He wasn't bloody when he left the scene. What did you do? Screen check him?"
"Oh, you know Sarg, those damn suicide squirrels."
