I'm concerned that some of the new security restrictions will start impacting peoples' health. What if diabetics can't bring their test kits, insulin and syringes on board? What if someone gets sick in the last hour of the flight and needs to use the bathroom?

Full body scanners containing nitrate detectors (most explosives contain this stuff) already exist and may be the best solution (for now). Certainly, the human error of blowing off the guy's father shows that no matter what kind of machines or high tech toys you have for security, human errors must be taken into account. I just heard this morning that the guy was helped to board without a passport, and they're looking for the person who facilitated that.
