Sorry, but you just dont know what you are talking about re: the Kinehans, try Google.
He may garner some legitimacy in the boxing world, but he cannot enter the USA, nor can he ever return to Ireland (without fear of being shot) without being arrested(nor many other EU countries).
The Kinehan cartel have been(and still are) involved in wholesale worldwide importation of drugs. They have been run out of Spain by the cops and fear of dying, and now reside in Dubai.
They have murdered several innocent victims, some by false identification, others by bad aim, and these are high profile cases waiting to be aimed should they have the balls to return to Ireland.
The Regency hotel shooting:-
Dublin Regency hotel shooting: one of six-strong gang 'was dressed as a woman'
Fortunately, both sides in the fued seem to be lying low at the moment, in fact many are overseas.
Also, as Graham says, the Irish government have gotten involved here, and hope that the relevant authorities listen, pay attention, and act.
