TSA implementing 'freeze drills' past checkpoint - KMSP-TV

Did you ever play freeze tag at school? It's now being done at Sky Harbor Airport -- but it's no game.

A YouTube user captured a TSA agent out at Sky Harbor ordering everyone to freeze. This is after they've gone through security.

Moments later -- he allows them to continue on. There's no mention of any security breach.

The TSA says this type of thing is known as an all-stop drill.

It apparently allows agents to practice in the event of a real emergency.
