No greater evidence that we are still at war with a very dangerous enemy:

"We are aware of numerous plots to kill people and to damage our economy," Dame Eliza Manningham-Buller, head of MI5, said. "What do I mean by numerous? Five? Ten? No, Nearer 30 — that we know of. These plots often have links back to Al Qaeda in Pakistan and through those links, Al Qaeda gives guidance and training to its largely British foot soldiers here on an extensive and growing scale."

Boring but essential human intelligence, surveillance with court oversight, greater attention to the borders, and keeping the pressure on al Qaeda in Iraq and elswhere: all these are part of the solution. But any complacency seems to me misplaced.
