So the would-be bombers from 21 July 2005 have been convicted.
I was interested to see that the reason London was saved from absolute carnage that day was because the ringleader was so inept at basic arithmetic that he miscalculated the ratio of the ingredients and created a relatively harmless mix instead of the deadly explosive that he had planned.
He was educated in Britain, failed maths GSCE and was obviously so badly taught that he could barely count.
Thank Heaven for our failing education system... I think!
