Again why make things up , why twist facts and why support a case if you can only make it by blaming the EU.
They have been very clear that the issues which would mean a non conviction are lack of any hard evidence , Irish extradition rules etc. It is also pretty clear that the whole mess of the wrongful convictions and the reason they got away was entirely a British failure in intelligence and the law services not down to the EU. There is barely a country on the whole planet that would extradite people 40 years after a crime when there is no hard evidence and certainly there is no country that extradited without a request.
I think we should start a sweepstake on what the EU will get blamed for next that is nothing to do with them.
I reckon England now winning the World Cup since 66, the abuse of Welsh language speakers in the first half of the 20th century and the Lennon assassination will be next to be blamed on the EU.
But it's gold the EU is to blame for not extraditing people where there is no hard evidence , so no prospect of conviction, where the extradition laws from the time which apply were pre EU and where extradition hasn't even been requested .
If you want anyone to have a go at over the fact murderers went free do and look at the West Midlands police
