We need to rethink our Idea of locking people up for any reason. In order to empty our prisons and deal with crime and terrorist an Illigals we need to do two things one we tell these people to leave this country and we give them a bit of time to arrange to be accepted in a new country. The other thing is if they don't leave and are they return we execute them
How long do you think Duncan would last in a Muslim country? Not long and that sounds prety good to me.
Actually deportation of criminals has been done before by any number of countries...tough love of sorts...and with some success - why not try this, with payment to receiving nations (perhaps in Africa) helping them financially and helping us too.
