1. Look at someone like Timothy McVeigh. He didn't want to die, and if he hadn't been caught, I wouldn't be surprised if he would check a bag and then skip out on the flight. Big, organized, brainwashed terrorist networks have plenty of young boys to take over when their fathers die in suicide misssions. But, small grassroots terrorists can't all go kill themselves, or they won't have anyone to further their agenda.

2. Average one minute delay per flight assumes that not every flight has no shows. How many people really check in for a flight, check baggage and then decide to leave the airport and go home, without their checked luggage? Obviously flights that have no shows are going to have to wait more than one minute so someone can rummage through the cargo hold and find the bag in question. The average of one minute means that if it takes 20 minutes to find a bag - for every 20 flights there is only one flight with a no show.

3. PPBM and scanning checked luggage are great ways of preventing problems if you ask me, for one major reason - they don't take away any of my freedom. I'd rather have them run my bags through an x-ray machine than have to get grilled under hot lights every time I want to fly. I'd rather have the bags scanned then have to have my car searched at random checkpoints around the airport. Bag scanning is better than having my phone tapped to find out if I'm planning on blowing up a plane. And so on.

4. Look how organized the 9/11 attacks were. Multiple people on multiple flights at multiple cities, all happening at the same time. Is it completely crazy to think that maybe the terrorists would think about blowing up 10 airplanes at the same time, considering how easy it would be?
