Might not be a good idea. Your government might get the idea to send all those criminals to the colonies again and you know how that worked out. You made a whole continent of gangsters and cowboys over here and Australia. We have enough criminals over here in political office and corporate board rooms, I'm not sure we have room for more.
I think if you could go back to where a large majority of Irish households had shotguns in the house and it wasn't against the law to have a revolver in the dresser at home or in a gentleman's pocket your criminal element might get a little shy, or at least a little more polite.
At least that is the theory and what we are working for in our neighborhood.
