ProPublica has found the NYPD site for allowing the public to track officers’ misconduct is shockingly unreliable. Cases against officers frequently vanish from the site for days — sometimes weeks — at a time. The issue affects nearly all of the officers in the database, with discipline disappearing from the profiles of patrol officers all the way up to its most senior uniformed officer.

ProPublica examined more than 1,000 daily snapshots of the database’s contents and found that, since the fall of 2022, the number of discipline cases that appear in the database has fluctuated often and wildly. Try to pull up the record for a disciplined officer and the site sometimes spits back, “This officer does not have any applicable entries.”

Since May 2021, at least 88% of the disciplinary cases that once appeared in the data have gone missing at some point, though some were later restored. As of this week, 54% of cases that had at one point been in the system were missing.
