Not a good day for this robber. The scooter rider witnessed a man robbing a girl in the street and tricked him into riding the scooter as a getaway vehicle.

The robber was shocked to find he had been tricked, when the 29 year-old scooter rider headed straight for the nearest police station, where police made an arrest.

Sometimes all you need is video camera, a loud voice and conviction.

This super impressive video shows two guys noticing a suspicious man photographing young girls coming out of a store and begin following him until they get the attention of the police, who make an arrest.

Even with the arrest, Jason Juniel, who took the video, posted it to Facebook so people could watch out for a creep like him.

[Jason] Juniel and [Broadus] Parker work for a tour bus company on Union Square. They kept at it until they finally got the attention of police, who then detained Brooks.

"The camera was in the bag angled up perfectly toward the hole cut about the size of half a dollar so the lens of the camera could see directly up a skirt," Juniel said.

According to SFPD, one of the officers took his camera and found more incriminating evidence, but only cited him under Penal Code 647 J2, disorderly conduct using a camera to look at women's undergarments.

Way to watch out for your fellow human beings.
