Here are two different police vans, one of them looks made for giving "nickel rides" if someone wanted to.
We used different vehicles depending on the number of prisoners. We had regular front facing vans and the ones where they sit sideways facing a metal partition that divides the van in half. We called that one the ice cream truck. Prisoners use to throw up back there all the time. I liked it better then the regular vans because you didn’t have prisoners sitting directly behind you looking over your shoulder.
