So basically you subscribe to the idea that "It's extremely unlikely to ever happen to me personally or anyone I care about, and I'd rather myself and thousands of people there every day be be minorly inconvenienced."? I see where you are coming from, and selfishly I agree somewhat. I know it's unlikely to happen to me and long security lines could be a pain. But I think it happening to ANYONE there, is just as bad as it happening to me or someone I know. So for that, I am willing to go through a minor inconvenience as long as it doesn't encroach on my freedoms.
