Whoops I have left £50,000 of stolen money lying about, how silly of me.
So what's more believable. A bunch of terrorists who are saying they are giving up their armed campaign and ending criminality within their ranks, going for one big pay off. Or a bunch of policemen going into a Republican area in Belfast, tiger kidnapping a family, robbing £28m from a city centre bank, then investigating themselves with another police force, then planting the money on an Irish businessman to make it look like Republicans. Then fooling EVERYONE including the British & Irish Governments again that it was the work of the RA.
