This reminded me of the time I went to Camden for a concert a long while ago. There were so many cops around the perimeter. A couple of my friends were wandering around during a break near the residential area, and this one cop went over right quick and stopped them. He said something like, "This is really not a safe area. Stay on site and when the concert's over, just get in your car and go."
Just the way he said it, the way he looked, kinda impressed itself in my memory. Nowadays, I've heard Camden is a lot calmer and is kind of experiencing a resurgence, although it's probably still not a good idea to wander outside of the tourist or commercial areas. Not that I'd know, I've never been back and don't plan to.
