1. As I understand it, the reason for the super red alert in the UK was uncertainty (which still exists) they'd caught all the plotters, which is a very good reason indeed.
    2.  Not that anything's perfect, but I'd rather the terrorists spent their energies trying to beat airplane security, which is rigorous and easier to make near-foolproof, then that they figured out how many less complicated ways there are to create mayhem in America. Look, here's a method of blowing up airplanes that can be foiled by making people put their shampoo in checked luggage and throwing away their Starbucks containers at the gate. That's hardly draconian police state action. Get a grip, gang.
    3. They didn't kill as many people, but the DC snipers, a pair of nowhere maniacs with a rifle, came a lot closer to shutting down our nation's capital through terrorism than the maniacs who flew an airplane into the Pentagon. That's the sort of terror action that worries me the most. Simple, easy, and no conspiracy with a potential for stool pigeons.
