OK, let's say "snap" and move on, Carol. I will suppose no longer.

Dianavan, I agree 100% with your "can't fight terrorism with military might" statement. It's the wrong size net for the fish you need to catch. In fact your statement applies even in the case of state-sponsored terrorism, which of course neither the London bombings nor 9/11 were.

Earlier today, when I heard that (one of) the bombmaker(s) was Egyptian and had been arrested in Cairo, it occurred to me that there will be those out there who will immediately shout "bomb Egypt". But that is the same mindlessness thar drives thugs to attack a sikh temple in the UK because they thought it was a mosque, or the early Crusaders to arrack christian villages in the M.East because the males wore turbans. But the truth is you can't fight bombs with bombs when it comes to terrorism.

Police work is indeed what is needed, and painstaking one at that. I confess I am rather surprised (pleasantly) at the swift progress made so far; these things can take years. I can only guess at the massive effort that has gone on to sift through the available evidence, and of course that mother's phone call was a lucky break.
