Richard Thompson Ford uses statistics regarding the demographics of New Yorkers arrested and prosecuted in the past to justify the highly disproportionate effect that the NYPD’s stop-and-frisk policy has on minorities (“Frisky Business,” PostScript, June 26).

Ford fails to realize that racism had a part in those statistics, too. Do blacks and Hispanics really commit 80% of the crime in New York, or are they just arrested and prosecuted at that rate?

The stop-and-frisk numbers are only consistent with numbers produced by a criminal-justice system that successfully arrests and prosecutes minorities at a far higher rate than whites.
