Anne Applebaum says that the Department of Homeland Security does not protect America against terrorist plots. Yes, she says, “[t]errorists have been stopped since 2001 and plots prevented, but always by other means.” She continues:
After the Nigerian “underwear bomber” of Christmas Day 2009 was foiled, DHS Secretary Janet Napolitano claimed “the system worked” — but the bomber was caught by a passenger, not the feds. Richard Reid, the 2001 shoe bomber, was undone by an alert stewardess who smelled something funny. The 2006 Heathrow Airport plot was uncovered by an intelligence tip. Al Qaedas recent attempt to explode cargo planes was caught by a human intelligence source, not an X-ray machine. Yet the TSA responds to these events by placing restrictions on shoes, liquids, and now perhaps printer cartridges.
