thats what i wad wondering to0 :/ . I even checked the anime convention in Connecticut's weapon policy page and they accept them so, i dont know why anime boston cant accept them. But , i assume it might have to do with the bombing. But it still doesn't make sense when other cons in near by states are fine with them.
