I think this decision is disgraceful.
There is not enough evidence to charge him, therefore according to Irish and English law he is innocent.
France has a different legal system, guilty until proved innocent, yet this crime was committed in Ireland not France, and as I understand it he is to be questioned by French Police, I am also under the impression, that the family of the unfortunate murder victim, have said that they wish to prosecute for civil damages, as I understand it, this means considerably less evidence of guilt is necessary.
To be extradited for questioning to another country is Bizarre, when there is not sufficient evidence OF GUILT according to the Irish DPP for a prosecution.what the hell is going on ?
