Barry Krisberg … said that it is difficult to determine what causes crime to decrease because there are so many possible factors…. He praised the police department’s community policing strategy, and said that Richmond has an effective police chief and a cohesive violence prevention plan. Krisberg also said that new research suggests a correlation between immigration and lower crime rates. He said that because most immigrants have come to work, they tend to keep their heads down and avoid criminal activity. “Increasing immigration into Richmond has probably produced a safer community,” he said.
