Xist, yes. The base cops scan plates and record video with a second smaller set of cameras. They also scan your id and checks the fbi computer for any warrants. They then hold you to contact that jur distraction to see if they want to extradite you. Then they release you to the grounds or transport you. Luckily with budget cuts if you do something in another state, they wont extradite you.
When it comes to regular cops, telling stories that go no where like Baltothewolf or talking about your fetishes is a good idea. I like to tellem I have a secret clearance, work for area 51 and how the white SUV up the road has me under surveillance.
Base cops consider talking a sign of guilt and in many cases purposely give you the stare or look and pause checking your id to see what you do. I gave a blind gentleman a ride to work and he ignored the officer at the gate. We got pulled over and questioned further and I explained he cant see. I think the officer took it personally.
