I guess most patrol cars have a glass bubble separating the rear seat from the front now. Back in the day, our City PD cars had a section of expanded metal welded in to the side pillar separating the driver from the rear occupants. An officer I rode with a lot very often brought people in with the imprint of the expanded metal on their face and head, especially if they happened to be cussing him, which was often the case. He could truthfully say that he never laid a hand on them, he just had to make a couple of panic stops between where he picked them up and the jail.
And that my friends is what we used to call a "Screen Test"
"Y'know Cap, that car busted that stop sign and it was all I could do to keep from gettin T-Boned."
He would just look at me and say " That boy looks like he was run over by my wifes waffle iron" and just walk away shakin his head...
