In 2006, DOI announced a commitment to collect, memorialize and issue all of the PPRs made by DOI to various City agencies since 2002. The effort is to ensure that corruption vulnerabilities already identified have been fixed.  PPRs illustrate DOI’s dual function of not only making arrests but also – unlike any other law enforcement agency – addressing operational vulnerabilities within a City agency. DOI has appointed a staff member to undertake this project of collecting all PPRs made by DOI and ensuring that the problems identified have been remedied. Since 2002, DOI has issued more than 2,370 recommendations, with most being implemented.
