Some very sick copycats?

My immediate thought too. Looks like an amateur copy, done because it
would be "funny".

I doubt it. I don't think a copy-cat would go to the extent of 4 almost
simultaneous incidents.

I think London got lucky this time.

One of the reports on BBC World service (30 minutes ago) had the bus
driver reporting a split open rucksack, with white powder spilling
out.

My suspicion is that these were real bombs, but the main charges
failed to detonate.

Modern high explosives are pretty insensitive, and it require a
detonator or blasting cap to get them going.

Perhaps they were constructed incompetantly, or home made explosives
were used which did not work.

We'll know in a few days, I guess.
