Gregory Grice, a 16 year old railfan, was detained by police in White Plains, NY early in June. Apparently someone called the police and reported him "kneeling with a device". He was actually taking pictures of trains at a public crossing. Four? police agencies responded.
He was questioned at the scene and then taken to a MTA police department building, where he was detained and finally released. He accidentally recorded most of the ordeal and a segment can be heard below.
He was eventually charged with a variant of trespassing and he has a summons to appear in court.
The response seems extreme for a kid near the tracks!
