This makes me wonder if I was scanned on my way through one of the many tunnels in NYC earlier this summer while I was vacationing there? There were about 15 lanes of traffic (toll lines) converged into two lanes to enter most tunnels. If what you say is common practice for the NYPD at events, certainly they would have something setup at tunnel entrances too.
