Which commission investigated systemic police corruption in New York City during the 1990s?

• A. Knapp Commission
• B. Mollen Commission
• C. Civilian Oversight Commission
• D. NYPD Reform Commission

Answer: (B)

The main idea here is identifying the specific inquiry that looked at police corruption in New York City during the 1990s. The commission that was set up in that era to examine whether corruption ran systemically through the NYPD and to recommend reforms is the Mollen Commission. It was established in the early 1990s and released its Final Report in 1994, documenting widespread misconduct, bribery, theft, and collusion within various units and precincts, and it spurred significant changes in internal affairs practices, supervision, and civilian oversight.

The other options don’t fit the timeframe or the famous inquiry: the Knapp Commission studied corruption in the NYPD in the 1970s, while the Civilian Oversight Commission and the NYPD Reform Commission are not the well-known 1990s investigative bodies focused on NYPD corruption.
