The "30-year low in violent crime" still puts DC ahead of every state in homicide rate. If DC were a country, it would rank somewhere around the top 20 most murderous. Venezuela, a literal failed state, has a lower homicide rate. Russia, the dysfunctional kleptocracy that it is, is less than a third as murderous as DC.
Might not the people of DC deserve better? Is it possible that problems exist in real life outside of "media attention"?
