I think that purpose statement implies good intentions - we all know measurement stats become the thing that is gamed to make one's organization look good and this is well documented for American law enforcement. Unless absolutely forced to, they simply do not measure things they do not want to report, i.e. prosecutors do not have to document racial backgrounds of accused to prevent racial discrimination from being proved in court (The New Jim Crow), crimes by law enforcement are underreported - especially fatal use of force - justified because "cop scared for his life" (Copoganda), tons of anecdotal evidence many cops will not investigate petty theft even when owners track down thief. The Wire kind of made fun of this "juking the stats" more than ten years ago (co-written by formal journalist David Simon).
