How to increase security without closing the door too tight
WHAT WE SHOULD DO:
U.S. officials abroad who process visas need better access to FBI databases to screen out suspects.
USE MORE TECHNOLOGY
Washington should help other nations adopt machine-readable passports. Facial-recognition systems could help verify passport photos.
MONITOR FOREIGN STUDENTS
Expand a pilot program to monitor the 500,000 foreigners in the U.S. on student visas.
AND WHAT WE SHOULDN'T:
Cutting temporary or immigration visas would anger allies at a critical time and could hurt the economy.
GIVE UP ON AMNESTY
U.S. security would benefit from bringing many of the 8 million or so illegal immigrants now living in the U.S. out of the shadows.
RELY ON BORDER CURBS TO THWART TERRORISTS
It's better to screen out wrongdoers at U.S. consulates abroad.
