Just a question to the Gen Con staff. I am aware of the current weapons policy, and was wondering if the events in Phoenix Comicon are prompting you to change your policy. Theirs was similar to yours and after this person was arrested, they did not allow anything that even looked like a weapon in (including cardboard shields). I hope you won't change your policy, I have spent about 20+ hours making a scythe for my daughter who is cosplaying RWBY for the first time and I would hate to have to leave it home (it's compliant with your current policy.)
For those of you that don't know, there was a subject at that con that came in dressed in costume with real firearms and posted pictures of police officers that were working security and threatened to kill them in those posts. (I'm a police officer and this kind of annoys me).
