We have four separate airside terminals with TSA screening on the airside rather than the landside. This results in more efficient screening (we have the fastest TSA wait times of any large hub airport) - but it also means that KCM would require four separate screeners. We've been told by TSA that they don't have the resources to provide KCM at four screening points while still maintaining their pax screening standards.
My hope is that we can create a departure setup at the airsides that allows people to leave the terminal without a screener having to be positioned there - that might free up the resources.
I think having KCM means that we'll probably get dropped off at the main terminal. And that would blow.
