Perv teacher’s nude Snapchat used as evidence in court

A 16-year-old girl who was victimized by pervert Brooklyn Technical HS teacher Sean Shaynak acted quickly to capture the evidence that sent him to prison, her lawyer says.

Shaynak sent a revolting Snapchat photo of himself with his penis sticking out of his pants, along with the caption: “The rip isn’t THAT noticeable, is it?”

The pic would have vanished in 10 seconds, but the girl took a screen shot, said lawyer Jeff Herman.
