I thought this was a good article, and very timely, by Mr. Andrew Branca:
"...In short, one would apply the usual five elements of a self-defense justification to evaluate such a use of force against others, just as in any other instance of self-defense. Those elements are, of course: innocence, imminence, proportionality, avoidance, and reasonableness.
When all required elements are present, the use of force was legally justified. If any required element is missing, whatever that use of force might have been it was not lawful self-defense.
One of the challenges to legally justifying the use of force against highway blockades is the element of imminence. Do people who are merely blocking a roadway represent an imminent threat against which some defensive force might be justified? ..."

Thoughts?
I find it comforting to think of putting the truck in 4WD and using the 800 lb-ft torque of my Cummins Diesel, but there are good things to consider before doing that.
