Can You Spot the Threat?

MSNBC has this interactive feature that lets you play the role of a security screener who sits behind a scanner to detect possible threats. You can flag bags for additional screening depending on whether they have firearms, explosives, or knives.

You have two minutes to screen as many bags as possible, and are then scored on how many threats were correctly identified and how many false positives were incurred. The more false positives, the longer the line would be.

On my first run through, I managed to get all the threats identified, but had four false positives in 20 bags checked.

It gives you an idea of what kinds of pressures the TSA screeners are under.
