Actually that's not true, if Ireland presents evidence of criminal activity to a UAE court and a request that he be extradited then the court will look at it and decide whether or not it can proceed but they don't have any evidence that's why when he was in Ireland and Spain he was never extradited and that's why he was free to go to the UAE. All we've heard from the MEDIA is that his father is head of a drug cartel and since he is his father's son he must be involved as well. That's not fair is it?
Tyson Fury hasn't sued Deontay Wilder for claiming he cheated in their rematch, Breland hasn't sued him either for claiming he spiked his water, these are allegations that could do reputational damage but neither have sued, does that mean they're guilty? Many if not most are saying to Wilder provide some EVIDENCE or SHUT UP!
Its not easy to extradite someone at the best of times. In addition, Ireland don't have a treaty with the UAE, and he's not been arrested in the UAE.
Kinahan has several options if he wants to clear his name, he won't take them though, because it will mean going to court.
1. Hand himself into the Garda and face criminal proceedings. (if he loses he goes to jail).
2. Sue the media in the UK and Ireland. However this would leave him open to disclosure requests that would assist any criminal cases against him.
Further to this. Coming back to the UK or Ireland would leave him at risk of violent reprisals from his enemies.
He's not going to do anything other than release statements, make threats, and press people to speak up on his behalf.
