In 2011, Memphis defied the national trend of declining crime rates in major U.S. cities. The rate of violent crimes per 1,000 people increased, from 15.4 to 15.8. This was the product of increases in murders, which rose from 89 to 117 cases, and aggravated assault incidents, which rose by 100 cases. A rising unemployment rate, which grew 1.2% to 11.1% in 2011, likely has not helped to reduce criminal behavior. With a current budget deficit of $45 million, Mayor Wharton says he may need to consider “taking boots off the street,” by laying off members of the police force in the near future.
