That's a maybe. But he's right. The citizens of the respective states should have the right to protest the federal government's actions without the threat of being run over. If the government disagrees with the stance of Sheehan and protests against it, let them take care of it. But it should not be the right of a citizen to take the issue into their own hands either.
I certainly don't want to see any violence done against the protesters but beyond that, I just don't care about them. I had my full of this crap back in the 60s and 70s.
