A group of close to 40 Baltimore businesses has signed on to a letter threatening to withhold tax payments from the city until it improves policing and other services. “When it comes to prostitution, public urination and defecation, and the illegal sale and consumption of alcohol and illicit drugs on the streets, we know these crimes are not as serious as the carjackings, shootings, and homicides that have become routine,” the letter reads. “But, as this past weekend proved, a culture of lawlessness rarely remains confined to petty offenses and invariably leads to the kinds of violence and tragedy we witnessed late Saturday night.”
