Al Qaeda targeting Britain

The Home Secretary has warned that Britain is facing waves of terror plots, most of which are now being orchestrated from abroad. He said:

They do look as though they are being directed from abroad, specifically by elements of al-Qaida. Secondly, they look as though they are being prepared strategically. That is, they fit in to a pattern.

He went on to say that the threat was seamless and required a seamless response:

The threat from al-Qaida is a seamless one. It is no longer capable of being divided into just defence or foreign affairs issues or domestic issues. There is a seamless threat and we must have a seamless response.

That's all very nice, Dr Reid, but if you can't keep extremists out of your own office how will you keep them out of Britain?
