Did the Bush Administration Botch Attempts to Stop the London Bombings?

I've read several articles today that indicates this may indeed be true - and heinous.

Here's one account, from AmericaBlog.

This isn't the first time we've screwed the pooch on something that would have prevented trouble. Given the large number of failures on 9/11 and the fact that despite massive amounts of money poured into homeland security and the "War on Terror", we're less rather than more safe, it keeps bringing me unhappily back to questions of whether 9/11 was at least something of an inside job.

That's the problem with liars: when they lie about everything, it's very hard to believe them simply because you can't imagine they would actually do something so so so atrocious.
