THE MAJOR OFFENSE BUREAU (MOB) WAS CREATED AS A RESPONSE TO INCREASING DELAYS BETWEEN THE APPREHENSION AND TRIAL OF FELONY DEFENDANTS IN BRONX COUNTY, THE RESULTING LOSS OF WITNESSES OR EFFECTIVE TESTIMONY, AND THE BELIEF THAT A RELATIVELY SMALL PERCENTAGE OF OFFENDERS COMMITTED A DISPROPORTIONATE SHARE OF SERIOUS CRIME. MOB STAFF ARE ASSIGNED SPECIALLY SCREENED MAJOR OFFENSE CASES AND ARE RESPONSIBLE FOR ALL STAGES OF THE PROSECUTION. THE VALIDATION REPORT INCORPORATES INFORMATION FROM PROJECT SUBMISSION DOCUMENTS; ON-SITE INTERVIEWS WITH MOB STAFF, DISTRICT ATTORNEY STAFF, JUDGES, AND DEFENSE ATTORNEYS; AND A LEAA (LAW ENFORCEMENT ASSISTANCE ADMINISTRATION) AND A NDAA (NATIONAL DISTRICT ATTORNEY'S ASSOCIATION) PUBLICATION DEALING WITH CASE SCREENING AND SELECTED CASE PROSECUTION. APPENDED INFORMATION INCLUDES EXEMPLARY PROJECT SUBMISSION MATERIAL, LETTERS OF RECOMMENDATION, CASE EVALUATION AND CASE MANAGEMENT FORMS, AND A SUMMARY OF ACTIVITIES IN THE BRONX DISTRICT ATTORNEY'S OFFICE IN 1975.
