Hollaback GirlA 28-year-old woman in New York who spotted a man taking pictures up her skirt as she was entering a subway station decided to turn her camera on the perv and took a cell phone picture that eventually led to his arrest. On Tuesday, the NYPD arrested Aaron Olivieri on misdemeanor charges of unlawful surveillance, attempted sexual abuse and harassment. With cell phone cameras becoming more and more popular, woman targeted by street and subway harassers are encouraged (when it is safe) to snap pictures of pervs to fight back. One website, Hollaback NYC, encourages victims to post pictures and stories of harassment and the NYPD encourages people who witness crimes to send pictures to 911 when they call.
