hello everyone, i just want to ask what are our limitations whene taking photos especially on public places... because a while ago i was in the city & i took some shots on the traffic light, then a traffic enforcer saw what i'm doing & after wards he approached me & asked what i'm doing, i didn't answered his question.. i just asked him "am i doing illegal here?" & we had a little argument... please guide me for my rights & limitions on taking pictures, thanks in advance...
