except I never planned to go to Anime Expo, so it doesn't apply.
frankly I don't see how some people can be afraid of someone in a costume posing for a bunch of photographer. In exchange for possibly getting in trouble, I get some realism in photos, play it safe and I get stuck with a paper gun. You can't have it both ways. You can be mature about it and use it properly to great effects, or you can dick around with it and get in trouble.
