Sir, my point was, what about those that are home born and grown?
If there is a foreign country where they are wanted, great.
What happens when they are either not, or the terrorism is enacted on your own soil. Where are you going to deport these then?
Those who are home grown are the vilest of the vile. They are traitors to the nation, and should be treated as any traitor and subject to said nation's laws regarding traitors.
As to deportation location; wherever the government deems fit. To Antarctica for all i care.
