Why was an Uzbeki Terrorist in the U.S.?

An Uzbeki terrorist mowing down bicylists in New York City while screaming "Allahu Akbar" is the poster child for why Muslims must not be permitted into the United States. Keep them in the Middle East, which they have ruined already. Don't let them ruin North America or Europe.

All of his family should be immediately arrested and confined in Guantanamo Bay until such time a prisoner exchange is arranged for the return of U.S. captives, now or fifty years from now. That would wipe the smirk off the scumbag's face.
