You mean, if my license plate number isn't in the system, I must be an Important Person who Should Not Be Noticed? Um, doesn't anybody see the rather serious security problems inherent in this? (Isn't this the kind of thing that the TSA and NSA actually exist to catch?)
I mean, say if I wanted to park a nondescript panel van next to a Federal Building, and its plates weren't in the database, the cops would respectfully not ticket it and leave it alone and have no record of its having been there?
Wow. And I thought I was going to have to steal the plates off a Representative's car, just for the giggle factor... Oops, did I say that out loud? Hi there NSA guys!
