Can it happen here?
Last year, 40-year-old Travis Wilson and his wife moved to a new neighbourhood in Louisville, Kentucky, after moving from Old Louisville where they counted the number of gunshots at night.
"I couldn't imagine how any child could grow up in an area where they hear frequent shots and not be dramatically affected," he said.
But last month, the violence followed him to his new neighbourhood when a gunman killed five former co-workers at a local bank.
Mr Wilson said he sometimes feels irresponsible raising a child in America, where nowhere feels perfectly safe.
