Ah! Chris Rea has added gun running to his misdemeanours who ,
Some say it was Erskine Childers,a noted hero of the Boer wars , writer of the semi factual novel 'Riddle of the Sands', who was found guilty of gun running for the IRA back in the Irish conflicts of the early 1920's, he was excuted shot by firing squad.
When all along it was Rea during his shenanigans of time travel, one of those guns was the pistol which Don Corleone was about to use to shoot dead 2 opponents to his Mafia family, realising that his actions were about to affect the timeline, he quickly nipped back replaced the gun, then whooshed back again to incriminate Erskine Childers, as a IRA sympathiser.
There is something very fishy about all this,, Childers was involved in a murky plot, to try and keep the Irish as part of the Union.
Alas ,it was not to be, as that very pistol was also used in the Murder of Michael Collins, in the SW of Ireland in a ambush, because Eamon De Velera couldn't stomach Collins attempts at brokering a deal.
Another Crime against humanity
Which whilst feasible, is totally untrue, Due to the fact Chris sold his time machine on E- bay
