Murder rates are down, but of course we would like them to go down more. In any policy discussion, first define the problem. The highest murder rates turn out to be in minority, ghetto areas, especially black neighborhoods. Next, ask if there is any evidence that a specific action will help. Giuliania turned NYC from one of the more murderous cities to one of the least by "aggressive policing", stop and frisk, data-driven policing, intervening in minor crimes, etc. On the other hand, cities like Oakland, Chicago and Detroit continue to have extraordinarily high murder rates. What do they have in common? Decades of Democrat hegemony. Want to reduce murder rates, especially murder of blacks and hispanics? Vote Republican.
