Whether Snopes has confirmed this or not, It'* happening. I did a little e-snooping of my own. While the National Auto Dealer Assoc. try'* to lay down alot of bullcrap about safety guards in place, there have been News People testing the waters and finding it easy to do.
Well dressed and speaking people aren't viewed as threats and as that News Crew proved, it'* often a walk in, walk out easy thing to do.
Having migrated from NY, I know whats Mike is saying. NY uses registration stickers alongside inspection stickers instead of Plate stickers with the VIN clearly displayed on them. And it is common for the NY Police to use that against the OEM tag to validate the cars belongs to you using the two side by side in view of each other. Very hard to cover that up. And any attempt to do so would get you pulled over by the watchful NYS State Police. Seems they should change the way they do things
