As noted
here, the Christmas Terrorist showed us many things.
1) The government is as incompetent at performing basic security as it is at providing anything else of value.
2) In light of 1), Al Qaeda and its allies are not terribly interested in launching attacks on US soil. It would not, apparently, be terribly difficult to do so if they actually had much desire.
3) Considering the attacks seen overseas, Islamic militants are mostly interested in attacking soldiers in Muslim areas and civilians who are living in occupied areas.
4) It is difficult to get someone who is both competent and smart to sign up for a suicide bombing mission.
to that I'll add
5) When government screws up, civilians get the shaft.
Have they confiscated all the equipment of the TSA employees who could have leaked that information? Have they all been supoenaed? For that matter, who's the last government clown who lost their job over a screwup? Brownie for Katrina?
She needs to light a fire under her own employees and figure out what happened here, not threaten civilians who exposed the TSA's incompetence in hiring people who could keep their mouths shut.
