Kick down 100 doors of self-proclaimed French pacifists, grab the women and kids, and haul them away. Then try again in Texas, with 100 NRA members.
Do this often enough and the NRA members might shoot back, but for the first 100, the results would probably be the same in Texas as in France. The shock or surprise factor is hard to overcome. As is the feeling that there must be some reason for the action or possibility of appeal. We did have our own internment camps in 1942, and there were no armed rebellions.
