No crowd shots (Score 1)

I was watching a local weekly concert from the roof of a hotel a friend of mine maintains and I was taking pictures like I do every so often on the roof. Apparently, I was creating concern among some of the attendees and federal investigators visited the front desk. They spoke with my friend and asked him to request that I stop taking "crowd shots". It's amazing to me. I was in a bright red shirt and making no attempts to be discreet. So much for freedom of expression.
