If anything it's the opposite: if you do anything slightly out of the usual - all the way to walking through a neighborhood that doesn't know you - there is a good chance someone will call the police. And that some patrol car will check it out just for breaking the dullness of the day.
Some of the cops who respond (because they might ALL head there, if it sounds fun enough), some will be smiling and relaxed and civil, while others will be very much looking for trouble and aggressive from the start. Such that for example, using plastic pistols in dark or day in public is a serious bad idea in the US.
