I haven't been hassled or anything, however I can since the a difference in tension in some areas. I did have a kind of funny thing happen though. I was out taking pictures of a President William McKinley's monument a while back and a cop started following me around. I didn't let it bother me too much because my battery was dying and I was trying to hurry up and get the shots I wanted. But around the time my battery finally gave, he started hanging back, like he was trying to spy on me or something...lol So with a dead battery and all, I still had juice in my flash, so I pointed my camera in his direction and flashed a few times. He disappeared after that?
I thought it was funny he didn't approach me instead of spying on me waiting to catch me doing something. He kind of reminded me of Inspector Clouseau.
