You, your spouse, and your child (or children) are driving along a freeway late at night. Up ahead, you see the flashing lights of a Trooper who has pulled over a car, so you slow down.
As you approach, you see that the Trooper is fighting with two civillians in what appears to be an all out struggle. You will be past the cars in two seconds.
What, if anything, do you do?
1) You have a cell phone
2) You are not near any known police stations
3) There is not much traffic in either direction
4) Your kid(s) is(are) age 5 or less (i.e. not in a position to help at all - substitute grand kids if necessary)
I've wondered what I would do while watching those police video stories...what would you do?
