Milwaukee has a historical gang problem. While the state of Wisconsin crime trends fall below the national average, the city of Milwaukee has long stood out above both. The city has seen similar declining trends to the rest of the country for property crime, but has experienced a mirror opposite to the nation for violent crime, with rates three times the national average and four times the state average.

Cities are allowed to have stricter gun laws than the state level, so instead of shaking their fists at state permit laws, Milwaukee could do something about their own laws. They could also seek guidance from other cities like Los Angeles and New York, which have experienced remarkable success rates in reducing gang related violence through community outreach.
