punsinhment for a class b Misdemenor

Under New York State Law, A B Misdemeanor is punishable by up to 90 days in jail or a year probation. Normally if you have no criminal record, the District Attorney would offer you what is known as ACOD which is an Adjournment in Contemplation of Dismissal and means if you stay out of trouble for a period of six months and the case is dismissed and the record sealed. However, due to the nature of the offense, the DA may not be so amenable to this. You may have to undergo a psychological evaluation and possible therapy in order to get the ACOD if it is even offered. Even if they do not offer you a ACOD you probably still be offered a reduced charge to a violation, which is not a crime and requires a fine be paid.  

Although I do not practice law in the State of New York, my research suggests that Sec. 245.00 of the New York Penal Code provides that:

"§ 245.00 Public lewdness:  A person is guilty of public lewdness when he intentionally exposes the private or intimate parts of his body in a lewd manner or commits any other lewd act (a) in a public place, or (b) in private premises under circumstances in which he may readily be observed from either a public place or from other private premises, and with intent that he be so observed."

Sec. 245.00 is a class b misdemeanor, which, once again, according to my research and pursuant to New York Penal Code Sec. 70.15 shall be given a definite sentence, and "when such a sentence is imposed the term shall be fixed by the court, and shall not exceed three months"

Nevertheless, if your are currently charged with any crime I suggest that you consult with and/or retain a criminal defense attorney licensed to practice law in the State of New York in the interest of obtaining the most favorable resolution of the matter as possible.
