Yeah, I'm surprised, the Brittish are surprised that the bombers where natives? I've been saying for a year or two now that if/when England is hit it will be by English-Islamicist citizens. Whereas in America we launch deep investigations into Imans who get up on the pulpit and preach anti-Americanism within our boarders, the English seen to be very liberal in their philosophy of how broad the "free speach" philosophy should be. When people hear how horrible western culture and England is over and over and over again every week or every day then they have a high propensity to act on these beliefs and that seems to be exactly what happened.
This isn't an "I told you so" thing, when America gets attacked by terrorists crossing our still wide-open US-Mexico boarder you can say the same things. But just like the American-boarder issue, it seems like a no-brainer that if you allow these Islamic fanatics to not only survive, but thrive in your country, they're going to act on what they've been indoctrinated in.
