If you show up at KCM out of uniform, and then get picked for a random full screening, you can ask for an escort by a TSA agent from the KCM to the normal security lane and not be subjected to the 3-1-1 rule.

The escort between to two locations is the key. It's worked this way for me before.

The August 2016 ALPA magazine describes this.

And no- I cannot find anywhere on the KCM site to back this up.
