What gets me is, we have the technology to follow these people that leave their country and train with and fight for ISIS and still they can come back to their own country and are allowed to go about their business like nothing happened. They should not be allowed back into their country and if they sneaked in, either drive them out or stick them in jail. They are here to carry out ISIS business when it suits ISIS. You don't join and train with a perverted bunch like ISIS just to leave when you like unless they approve of it, they are time bombs just waiting to explode at ISIS command.
