John Kosinski – NY State Bar # 2452084
Deputy Bureau Chief in the Queens District Attorney’s Office
Law Professors filed a grievance regarding John Kosinski’s professional misconduct in People v. Anderson. In Anderson, the Appellate Division reversed a conviction because Kosinski disobeyed the trial judge’s pretrial ruling, made prejudicial remarks that “were clearly intended” to suggest the defendant’s propensity for criminal conduct, denigrated the defense, and vouched for his two key witnesses.
All of these actions violated some of the most basic rules for prosecutors. Far from being publicly disciplined for his past misconduct, Kosinski has been promoted, and is currently a Deputy Bureau Chief.
In this role, Kosinski stands as an example to more junior prosecutors. His promotion through the ranks sends a message to other prosecutors in the Queens District Attorney’s Office (QDAO) that misconduct will be ignored and that the key to promotion is “winning” cases instead of seeking justice.
Kosinski’s misconduct in Queens was far from unique; serious misconduct at QDAO has been regularly reported for years.
Powerful positions require the highest accountability. We cannot reward prosecutors for breaking the rules.
