Nearly a decade after five suicide hijackers with expired U.S. visas helped 14 comrades carry out the Sept. 11 attacks, the Department of Homeland Security and Congress have yet to come up with a fail-safe way to check foreign visitors in and out of the U.S., leaving an unknown number unaccounted for inside the country.

Fail-safe? Many would settle for reasonably efficient.
