How do you suppose under-reporting property crime (provided this is actually happening in any major US city, of course) could lower the homicide rate by 40%?
But actually, here's the real truth, buried in the article:
"In Mosby’s last two years in office, 2,186 people faced felony gun charges. Mosby dismissed about 34% and another 30% received plea bargains, mostly without imprisonment. In Bates’s first two years, the number of cases increased a bit, to 2,443. Bates only dismissed 19% of the cases, and only 10% received plea agreements. The rest were convicted – an increase of about 1,000 people sent to prison – which includes a 70% increase in homicide convictions."
They put more violent people behind bars.
