I seen it work, kind of first hand. A number of years ago when the Garts at 92nd and Sheridan was still Denver Sports, I went in to get the latest thing I couldn't live without. There was a kid in front of me that got finished with His paperwork a few minutes before I did, so He went into the system first.

Finished mine, and started the wait/look thing. about the time that I started thinking to myself that this was taking a bit longer than normal, I was looking towards the front of the store, and noticed the 6 Westminster cops heading back to the gun counter.

The 3 biggest ones surrounded the kid, who was kind of obilvious to the situation. When everybody was in position, they tapped him on the shoulder, asked him questions for a couple of minutes, threw the cuffs on him and hauled him out of the store..

Wasn't close enough to find out what it was he was suppose to have done.
