Justice for the 21

I see there are calls in todays Birmingham Mail to back those fighting for a new enquiry into the Birmingham pub bombings. Why not after nigh on forty years it will be almost impossible to dig up fresh evidence so there wouldn't be a lot of chance of finding anybody to convict. Mind if they wait another 10 years they can be almost sure that anybody who planted or made the bombs will almost certainly have died of old age.

Does anybody think that if new evidence was unearthed that there would be the slightest chance of anybody being charged. What if for instance new evidence was found against the 6 that were originally convicted what would happen then? The reason they were released was because some of the evidence presented against them was proved to be unsafe.
