London Bombs

this sort of agrees with this, but also not.

The police were confident for the first few days last time that the bombs were timed. It's possible that the police were wrong, the timers were faulty, or that the timers were deliberately set short to make them suicide bombs.

Things were different the second time. either the bombs were deliberately crippled by the bombers to protect themselves, or by the bomb-builder to compensate for the possibility of faulty timers.

Goe, not blowing anything up today.
