US Journo Beheaded By British ISIS Fighter

Reports are that the Brit was fighting alongside ISIS fighters and actually took the head off the US journalist. There are reports that the Brit confused James Foley with Axel Foley (a character from a US movie Beverly Hills Cop II) who basically is a bad ass cop who has no discipline and screws everything up.

Axel Foley was also in Beverly Hills Cop I (the first movie).

"He also said the government would "redouble" efforts to stop Britons travelling to fight in Iraq and Syria."

Seems like the most logical thing to do would be to let them leave and refuse re-entry. Not the kind of people you want around to begin with.
