I've often wondered why there hasn't been more incidents; and I always tentatively conclude there just might not be that many real deal terrorists here. Although they much prefer high profile and kill rates (and this incident certainly qualifies as high profile), they could be far more effective in bringing us down with far more easier and numerous acts. If they just picked a dozen random theaters on any given Saturday night with a few handguns or small IEDs, then the next week the crowds lining up outside a sports or music venue, then supermarkets the following week etc. All with low casulties that would add up quickly...our economy would tank in no time. While many of us would grab arms and run out into the street after them; we tend to get a little sqeamish at the thought of something possibly happening to us or our loved ones at any old unexpected time. People would stay home in droves and we would begin to crumble.
I have to believe, given how much they wish to destroy us - that there just aren't that many here. You won't take us down with a spectacular event every ten years, five or even every couple years. That just p*zzes us off and gives us time to find the groups responsible and retaliate. I don't know about you, but I didn't change at all after 911...did not feel fearful nor even a little concerned. Nor will this change me. I still feel relatively safe and removed from any incidents like this. I likely would not feel so if my gas station down at the corner was blown up one week and a grocery in KC or Chicago was targeted the next.
