17 People Who Died in the 7/7 London Bombings Were Actually Alive Immediately After the Attacks

Considering that 52 total died, that is a high number to die later on. You have to think some of these victims that didn't die initially were actually "offed" by agents because they were unwanted witnesses to what really happened.

A.P. also notes that 17 is one third of 52 = 33%
