It's not so much a change for me. I've always considered such things possible. Maybe that's why I'm not panicked.
On this point, we agree. It's not so much a change for me either, since we've always *known* that sooner or later, terrorism was going to hit our shores. The problem with our foreign policy over the years, is that we were never really inclined to deal with terrorism, as long as it occurred somewhere else. As soon as it hit our shores, all bets were off.
So while we're not panicked, much of society is. We must *all* be aware of how our actions might cause others to panic. The same way you're not going to leave a bunch of white powder "laying around" in a public area (even if you just spilled your Equal while pouring it into your coffee) or yell "FIRE" in a crowded theatre, you or I (or this jerkwad) shouldn't be running through security - even if he was just through it.
Did the security people *know* for fact he wasn't bringing a bomb back in? No. Just because he left the airport because he forgot something, shouldn't mean he doesn't have to go back through security - or wait his turn in line to do so.
Since we're now officially arguing our respective points to death, and neither one of us is going to give, I've nothing more to say on the topic. We'll just have to agree to disagree.
