During a public safety town hall Monday, Bexar County District Attorney Joe Gonzales blamed the recent string of shootings of San Antonio police officers on the state’s open-carry firearms law, which he said prompted a rise in violent crime. However, at least one legal expert questions that logic, saying multiple factors played into the shootings that injured five officers over a 12-day period. What’s more, violent crime has actually declined in San Antonio this year, according to SAPD crime data. “When you talk about the incidence of crime, it’s all just so devilishly difficult to talk about what are the root causes of crime,” said Gerald S. Reamey, a retired professor at St. Mary’s Law School who also worded in law enforcement.
