agree, not a police problem. not really a southwest problem either. "Go to the main ticket counter for information" is a reasonable request. Nobody was losing anything by leaving the secure gate area - no planes, no chance of flying that day. why not just do what was requested? You're not magically getting a flight because you bully some gate agent who didn't cause this mess.

If you really feel like SWA, or the police, did you wrong, get an attorney and take it up with them in court. an airport gate is not the place make your stand.
