Bruce Schneier shines some light on the woeful state of security at airports
If some copycat terrorists try to bring their liquid bomb through airport security and the screeners catch them — like they caught me with my bottle of pasta sauce — the terrorists can simply try again. They can try again and again. They can keep trying until they succeed. Because there are no consequences to trying and failing, the screeners have to be 100 percent effective. Even if they slip up one in a hundred times, the plot can succeed.
The same is true for knitting needles, pocketknives, scissors, corkscrews, cigarette lighters and whatever else the airport screeners are confiscating this week. If there’s no consequence to getting caught with it, then confiscating it only hurts innocent people. At best, it mildly annoys the terrorists.
This scares me, especially when you realize how lax the security is at some of the smaller airports. They could try getting these “liquids” through some smaller airport and people wouldn’t even know.
