Who's The Security Risk?

So another dim bulb supposedly sent by al Qaeda has tried to blow up an American jet preparing to land in Detroit. Predictably, Homeland Security has "tightened" security rules in the aftermath. So far, we don't know much beyond the flight started in Nigeria, flew to Amsterdam, and then to Detroit. How this mope managed to get explosive materials on the flight remains to be seen, but the new rules we're likely to see will mostly make travel for the rest of us more difficult.

Am I missing something, or should we be doing things to make life difficult for al Qaeda and its hangers-on, rather than the vast majority of travelers? Some reports indicate this guy smuggled his explosives in his underwear from Nigeria. Now, everyone flying is going to be restricted to their seats for the last hour of their flight and won't be allowed to have anything on their laps during that time (including laptops and pillows). Presumably this would be to prevent the rest of us from setting fire to our pants (as this clown apparently did) while hidden by a blanket (or a laptop?). Wouldn't it make more sense to ensure that these jerks can't carry on explosives in their pants while the rest of us are carrying on laptops?

There's already been a report that U.S. officials were aware for two years that this particular Nigerian "could have terrorist ties." Despite that, he wasn't on any lists preventing him from taking commercial flights into the U.S. What's the point in knowing of potential terrorists if you don't think it's worth keeping them out of the U.S.?

What's wrong with this picture? If the Nigerian airport is unable or unwilling to adequately screen passengers leaving the country, wouldn't it make sense to prohibit flights originating there to land here? And if the passengers on this flight were also screened at the Amsterdam airport (which supposedly has a "good reputation for security"), what on earth happened?

In the meantime, the rest of the traveling public will be subject to more ineffective inconvenience and discomfort while flying. Bring on high speed rail service.
