Company put out a memo about that.
KCM point, random check, in uniform, TSA Pre-check, leave your stuff in your bags, no problem
KCM point, random check, OUT of uniform, regular passenger screening and everything better be "normal passenger" compliant, or you're not going to have a good time.
I figure it's a pretty easily policy to understand and follow. If I don't want the hassle, I can wear civilian clothes and travel with "3 ounce inna bag" rule. But the policy reads like you're absolutely rolling the dice going through the KCM point with civilian clothes.
