'Exonerated':or 'Within NYPD Guidelines' - The conduct occurred but did not violate the NYPD's own rules, which often give officers significant discretion.
'Substantiated':The misconduct occurred and it violated the rules. The NYPD has discretion over what, if any, discipline is imposed.
'Unsubstantiated':or 'Unable to Determine' - The alleged conduct was investigated but could not determine both that the conduct occurred and that it broke the rules.
