It might even be counterproductive.
Imagine the media coverage. Pick the scariest looking person, bait them, and get something damaging on film.
The purpose of a march is to get positive press that changes minds or scare politicians with numbers. With the way that the news is run by people who hate guns our numbers would be ignored or under reported. Then the type of people involved would be twisted or outright lied about.
I really wish that a march would work, I think we could get the support.
