"Who killed Channing Day? David Cameron was responsible for her being in Afghanistan when he had the power to end the pointless war in which she lost her life. At the current rate, more than 100 British soldiers will die before the end of 2014 -- the supposed exit date for the British army. The blood of every one of them will be on the hands of David Cameron."

There is another way to stress that. You will sometimes hear/read "each and every one". IMO, more useful for speech (in relation to the "everyone" vs "every one" distinction) than in writing, though.
