Bruce Schneier explains why he thinks the metal detectors that have been installed at major league baseball parks this season are “pure security theater – they look good without doing anything to make us safer.”
“As a security measure,” Schneier writes, “the new devices are laughable. The ballpark metal detectors are much more lax than the ones at an airport checkpoint. They aren’t very sensitive – people with phones and keys in their pockets are sailing through – and there are no X-ray machines…”
First of all, security gear needs to be credible, Schneier says, then goes on to discuss other aspects of what he considers an ill-advised move.
