How to Security Officer 202?

[Grek]

OK, rather than further comment on Grim Sleeper, how about I post the one I've been using:

"Hello, crew member. You are being detained as part of an ongoing investigation. While you are not necessarily suspected of a crime, your compliance is still required. You will be scanned for forensic evidence and your belongings will be searched. While this happens, you are invited, but not required, to explain your recent actions in as much detail as you feel necessary. Compliance will ensure a prompt release after the search is completed. Resistance will lead to brig time."
