This is the 200th episode for Rollins and the 450th episode for Fin.
The act generally known as "serial grinding" or "bump and grind", which involves "accidentally" bumping into someone in order to touch their intimate parts or to cause their own intimate parts to be touched, falls under New York Penal Code 130.52 "Forcible Touching". Forcible Touching is a class A misdemeanor and can carry a sentence of up to one year in jail, or three years probation, and a fine of up to $1,000. If the victim of the touching is 17 years of age or younger the perpetrator is required to register as a sex offender for a minimum of 20 years.
In the state of New York if a person commits the crime of Forcible Touching (such as the firefighter being interrogated) and has been previously convicted of Forcible Touching or Sexual Abuse in the Third Degree or Sexual Abuse in the Second Degree two or more times within the previous ten years they are also charged with Persistent Sexual Abuse, a class E felony which carries a penalty of either five years probation, or if incarceration is deemed appropriate, a minimum of one year in prison and a maximum of four years.
The plot is reminiscent of the case of Isaac Baichu, an immigration screening officer sentenced to four years for one case of coerced oral sex.
