i think europe should shut down the schengen borders. then each citizen would get a rifle and ammo at a local police station and a shade card. then, on a specific date, after midnight, the hunting for foreigners or non-natives would begin. it would be all live streamed by all tv stations on the continent as a warning. then, after few hours, europe would be cleansed and money made from the live streaming would be used for the cleanup. there ya go. problem solved.
