Lengthy searches as those people entered the Dome WERE worthwhile; this situation would be ten times as bad if those searches hadn't been conducted.
Were people allowed to enter and leave the Dome during the day? I'm wondering how those people got in there with guns.
They evidently stopped searching them as the crowds grew, to speed up entry into the Superdome.
I hear what you are saying but in an emergency , if you give up the right to defend yourself you become a potential victim. I posted a month or so ago that a shelter here said no pets, no alcohol and no guns. 2 out of 3 was enough for me not to condider it.
