I went to the lake today where I go all the time, and there were some cops in the parking lot talking to a lady. It looked like she hit a car while parking, no big deal. I had my camera, so I figured what the hell I took a photo and the male cop turns around and yells "That is unacceptable, stop right now!". I'm a good guy, I don't want trouble so I say no problem, put my lens cap on and start to turn away. He calls me back over to him, I go, he asks who I am. I say "I'm Todd" to which he responds "That means nothing to me" (lol?). Him and the female cop start yelling at me about how they are trying to investigate something and I'm interfering, I say that I was leaving. He keeps yelling at me (how do I know that's not a knife or a gun?), the female cop drags me off by the arm asking in what universe I think its acceptable to take a photo of police. Mind you, I know I'm well within my rights, but I don't say anything confrontational. She takes my liscense and heads to her car, telling me she'll arrest me for obstruction of justice. She doesn't come back, but sends someone else over with my lisence who tells me I have to leave, now. Still not wanting trouble, I say ok no problem, and I leave. Again, I know I was well within my rights and I could have made a whole issue of it, but honestly I wasn't trying to cause any problems. I just took a photo, the guy said stop and I did. Then they decided to call me back and go all NYPD blue on me.
