Redalways took the words out of my mouth too. Burden of proof is "beyond reasonable doubt" in criminal case.

The fact is, and always will be, mistakes do happen. Let's not forget Birmingham 6, Guildford 4 etc. I imagine (I don't know as I was only a few months old at the time of the bombings) a proportion of the British public was calling for the death penalty to be reintroduced when they were convicted. That would simply have been the execution of another 10 innocent people to add to the death toll of those two awful events.
