Nah... all you have to do is get the word out that a few of the drivers were pulled out of their car and beaten or shot... if the cars stop slowing and flatten a few protestors, just as effective as shooting. and better yet, the likelihood of a liberal being the one to mow down a protestor is pretty high in this area.
Rumors work ...
So far, all the videos I show indicate the protestors are bringing their own cars and turning them sideways to block the traffic.
SO you need to first roll their cars over into the ditch, and then “join” their protest by lighting cars on fire. Then you can go after your oppressors and free yourself from their clutches.
