Arrest of sex offender in new case sparked questions on registry. Here’s how it works. Updated Feb 05, 2021; Facebook Share STATEN ISLAND, N.Y. — Following the latest arrest of a registered sex offender who authorities allege used Instagram to try to lure a 12-year-old girl to a mall meet-up, questions began to arise regarding the inner-workings of the registry process and the restrictions placed on those convicted. Readers expressed confusion over why Ryan Behar, 42, of New Springville, who was first arrested in 2018 on charges he tried to coax a 13-year-old child to his apartment for sex, was not on the state’s online sexual-offender registry (he was a level-one offender, and thus not listed). Some asked questions about how offender levels are determined and what that means for the convicted and their neighbors.
