You may be right. The best way to tell if they are effective is to check their track record. So we can look to places that have been under democrat control for a long enough time to develop a track record. I live in Baltimore. It's been under democrat rule for 50 years. It's among the top ten most dangerous cities every year.
Of the top 10 most dangerous cities, all have a democrat mayor except Springfield Mo., which I believe has a Libertarian. I'm not sure what you are getting at by cherry picking Billings Montana and their measly 51 murders. Republican cities have their own problems as well, but, if you are trying to say that democrats have the best record for safe cities, we'll just have to disagree. Democrats continue to do things like, "sanctuary cities", support BLM, no cash bail, shoplifting under $1000, states attorneys that won't prosecute criminals, and demonize the PD. What do they expect to happen with such stupid policies?
To determine which cities in the United States are the most dangerous, we compiled data from the FBI’s Uniform Crime Report and viewed each city's violent crime rate. Violent crimes include: murder, rape, robbery and aggravated assaults.
