I can. It's against the rules. You know...kind of like the rules that the kids want to put in place for other things?
"Let's break rules and walk out of class, so that we can get lawmakers to make more rules that people won't break, even if they're insane, and "protect" us in our gun-free zone. Because only we can break rules, and only when we want to get a message across."
I guess I am one of the ones who fails to understand.
Personally, I'd love it if Capitol Police surrounded the march and arrested for truancy anyone who left before every word of every federal weapons regulation was read over the microphone. You wanna protest and get more laws? Better hear what's already on the books.
