Turning radius of late-model Chrysler minivan: Curb to Curb : ft 39.1
So, I guess they did a multipoint turn there, right past the gate, and were shot while doing it.
I do hate people who try to throw U' turns where there isn't space, I've never considered shooting them and their passengers, though.
To do it right in a Chrysler minivan you’re forced to build up some speed and use the E-brake.
