As my first offense in NYC i have been charged with menacing weapon 2nd degree misdemeanor, what can i expect and is it likely to get dismissed?

Each DA's Office in NYC has different plea policies, however, speaking generally if this is your first offense it is likely that you'll be able to resolve it with a non-criminal resolution to your case. With that being said, the weapon component will probably play a large role in the DA's offer on your case - as you can imagine menacing with a stick is treated much less seriously than menacing with a gun for instance. With that being said, your best bet is to go through all of the specifics of your case with your attorney and he/she will be able to best advise as to their expectations for the resolution of your case.
