After reading some of the discussion about having some kind of CCW Identifier (badge, sash, or drop down panel) I have to conclude that this an answer looking for a question.

The theory is that if there was some kind of incident, an armed citizen would display this credential and be less likely to be shot by responding police officers. The bad guys can’t get these? Who says the police are going trust people wearing them? If you are at ground zero of an incident and holding a gun you just have to hope that the police are observing your actions rather than simply seeing you as a “threat target.”

If you are standing there with a gun you are forcing the police to deal with you immediately and I would rather have the police deal with me after they have a handle on the situation. Once the police arrive on scene I want to be holstered and I want to have moved to a location where the police can deal with me on their terms (meeting the police in the parking lot would probably be best), hands up and identification out.
