The problem with all these conspiracy theories
Especially those involving governments - is that governments change round so often, that it would be impossible to keep such a conspiracy running.

The only interesting thing in that regard, is that yesterday's bombing had 4 bombs, as did Madrid and New York. And no, I don't think this is a clue that it is some weird conspiracy, just an interesting factoid.

I thought there were 5?
Edit: 3 tube bombs and a bus, according to BBC. Right you are.
