Disappearing from the UK

Another murderer has disappeared from an Open Prison in Scotland. So how easy is it to just walk out the gates to go down the shops and disappear?  Very, very, easy, indeed. A prisoner can have, about, an eight hour start and if he has plenty of money tucked away, in foreign parts, just what does he do?
From Castle Huntley, near Dundee, it is a quick drive over to the West Coast of Scotland, where you may choose a ferry to Ireland, from three ports Ardrossan, Troon or Stranraer. Ferries to Northern Ireland go from these ports on a "bus service" basis. You do not need a passport and as you are not yet 'missing' no watch is being kept for you.
From Belfast,if you head to the Newry, Warrenpoint area you can sit in the Warrenpoint Inn and view Southern Ireland or Eire, across the river Meath. You could swim, but why bother, as tourists move back and forward, crossing by boat. You need a passport to ENTER Britain but not to leave it to enter Europe. Under the Schengen agreement, all customs points and borders between members of the E.U. were taken down and people were allowed to move, freely, between all member countries.. Britain refused to sign and kept customs and border controls, but only for people entering the UK.
So you are now in Europe and it is only tea time !!!! You have another four hours or so before the balloon goes up! By which time you could be on a plane heading for anywhere in Europe and freedom. Sure international warrants will be issued and your picture will appear on some cop's dartboard but as long as you stay in cities and crowded areas, where a strange face does not stand out, especially a non sunburned one, you have comparative safety to live out your life, assuming that you had put away enough for that rainy day in the first place!!!
I have never understood why prisoners,in Open Prisons, are not electronically tagged for the very reason that they may just not bother to go back there. Perhaps it is cheaper, just to let them go !!!!
