Huh?

Arrived at the San Diego Trolley system's station at Qualcomm Stadium a little after 8:30 AM today to take the ride to the Convention Center for the first day of Comic-Con.

This station is elevated above the Stadium's parking lot, which basically means one can possibly park under the structure of the station itself. I've gotten into the habit of doing so under the eastern section of the structure. But when I approached that area this morning, I was waved off by security guards, which was the first surprise. So, I went around to the western section to park and proceeded into the station.

Next surprise was after purchasing a trolley boarding pass for the four days of Comic-Con. I spotted several police SWAT officers exiting their vehicle, which had parked under the western area of the station's structure.

I then spotted several men walking away from the station to a position where they lined up and each placed his hands on top of his head with fingers interlaced, a position I equate with the person being arrested.

So, I'm wondering: What is going on here?

I glanced back towards the men 2 or 3 minutes later and saw all of them drop their hands from their heads, walk over to another spot, and then huddle up for what was obviously some sort of discussion.

That's when the light came on: This must have all been some sort of police training exercise!
