As we seem to have returned to talking about the religion of peace, love, and public amputations ... I'm wondering what the odds are that it was an Islamic terrorist group which was responsible. Still seems a little low tech. It's not as easy to park a van full of high explosive in Boston as it is in, say, Kabul or Damascus or anywhere in Pakistan.
By the way it crossed my mind ... short trip, eh ... that making a nuclear bomb is not all that difficult ... all you need is a can of the good stuff ... weapons grade stuff. Pay a visit to Radio Shack, and, bingo, you are in business. Oh, some assembly required.
I was expecting the next big attack to be nuclear. There's also enough second hand warheads, already assembled, in Russia. I suspect lots of them are for sale. You know, some entrepreneur who wants to raise cash in order to buy a Premier League team. Perhaps terrorist groups have despaired of the BIG demonstration, and are reduced to using pressure cookers in order to express their love for god.
