An arrest is not a conviction, so there is nothing to worry about or "expunge" (which is not a possibility in NY) unless and until you are convicted of a crime. Get an attorney who should be able to insure you don't have a criminal record.

Unless there is some local ordinance, New York's Penal Law does not have a charge of "disorderly intoxication." There is a charge of disorerly conduct, which is a violation and not a crime. New York does not expunge. I suggest you retain a criminal defense lawyer asap.... especially if there is a chance there is surveillance video that would exonerate you that needs to be obtained before being taped over.
I am a former federal and State prosecutor and have been doing criminal defense work for over 16 years. I was named to the Super Lawyers list as one of the top attorneys in New York for 2012 and 2013. No more than 5 percent of the lawyers in the state are selected by Super Lawyers. Martindale-Hubbell has given me its highest rating - AV Preeminent - in the areas of Criminal Law, Personal Injury, and Litigation. According to Martindale-Hubbell”AV Preeminent is a significant rating accomplishment - a testament to the fact that a lawyer's peers rank him or her at the highest level of professional excellence." Fewer than 8% of attorneys achieve an AV Preeminent rating. I also have the highest ranking – “superb” – on Avvo. Feel free to check out my web site and contact me.
