Just a friendly reminder to watch yourself at those public pools: a Catholic high school teacher pleaded guilty today to using a hidden camera to record the girls' locker rooms at the Lasker Pool on 110th Street the YMCA pool at 224 East 47th Street last summer. "Peeping" Tom David Canela—chairman of modern languages at the private, all-girls St. Jean Baptiste High School and a part time lifeguard—faces up to a year in jail. We bet this never happens at the dumpster pools.
