I wish this were the case, but they seem to disproportionately lock up African Americans while giving the rich white people a free pass on crime.
Oftentimes, one finds a feedback loop between arrest rate counting and instances of crime counting that means all kinds of confounding factors enter into the number (including distribution of police patrol resources and likelihood police will let an infringement off with a warning).
Year after year the random samples of victimization correlates with arrest rate by ethnicity.
