Carry conceal or install cow catchers on your front bumper will solve most of these problems.

or install cow catchers on your front bumper

Hey, just got an idea...install 3 chainsaws on the front bumper with some kind of starting system to fire them up. Mount them vertically where they don't stick out too far. Maybe protesters would not get right up on front of the vehicle....
