BBC: Dummy explosions caused incidents in 3 subways.

What is a dummy explosive? One that should have detonated but didn't?

In the spirit of "conspiracy-think" I'd suggest they were dummy-bombs used to distract authorities while doing a Big Bad Thing somewhere else.

Other than that...I can't imagine- I also heard the bombs were made from the same stuff as the 07/07 bombs- and that they had poor quality "stuff"...hence the lack of firepower.

Still early in this event...

Did the BBC explain why people might be setting off dummy explosions?
