I've think you've hit on the important portion we're trying to remedy today, and that is the question of lawful authority.
When we deal with companies, we provide them with a facsimile with our letterhead on it and a supervisor's name. Or we have a personal relationship with them so that I can phone and say, “Hi, it's Earla-Kim.” However, we encourage people when dealing with law enforcement officers to be sure of who they're talking to. People will impersonate us. Certainly we ask them to check identity and be certain about who they're speaking with.
