ad-o, the Stockholm terrorist was originally from Uzbekistan but is that really relevant?
The recent terrorist attack here in Westminster, London, was from Kent. He was a loner. His poor mother is distraught about it.
Extremists come in all shapes and forms, vast majority of immigrants would never do something like that, they like being where they are now.
Wonder how you would feel if the Stockholm killer was Swedish. As many above have said, Anders Breivik was no immigrant.
