I was at the Fusion Fest at Hornimans this afternoon with my friend and our children. I saw an older man aged late 50's, 60's hold his camera at his side and take a photo of my daughter.I followed him and witnessed him take several more photos of children discretely with the camera at his side. I told the police and they checked his camera. They walked him home and told him not to go back to the festival. He said they were atmospheric photos of the event and the police confirmed there were pictures other than kids on his camera. The man may have been innocently taking photos however I am confused why he wouldn't look through the lens and take them. Why would he hold a camera by his knee, press the button and then walk quickly away.
