For the record those pics were taken at the last minute when I decided it would better help my story. They were way closer then that and slowed down over my building. Like I said before, I've lived in this neighborhood for a few decades, if this were a normal occurence I wouldn't have been worried about it. This copter was in the same area, so if there was a police investigation it would have been very clear by the presence of cops other then one lone helicopter. But I'm reassured and appreciate all the comments I guess it was just a coincidence.
