It seems that it's acceptable to post in support of civilians using guns in public and to suggest how to use them in the middle of a crowded cinema but It's not OK to disagree with those comments.
Probably an effective way to have the pants sued off you and get locked up for a long time is to take pot shots at another killer gunman amidst a group of innocent people. You won't walk out of it in a torn shirt, bloodied but unbowed, with the crowds cheering you and the police patting you on the back while the background music builds up to a crescendo. You may well, instead, share the same morgue as the other guy.
