The Early Case Assessment Bureau (ECAB) screens all arrests that occur in Brooklyn, determining whether a prosecution will be declined or will go forward and if the latter, what charges will be brought. ECAB staff members interview police officers and, in some instances, victims and witnesses. The bureau drafts the charging document (i.e., the complaint) upon which the defendant will initially be arraigned, and prepares supporting documents and notices to be submitted in court. Assistant district attorneys in the bureau also staff and supervise prosecutors in the arraignment court parts in Brooklyn’s Criminal Court.
