In this Feb. 26, 2013 file photo, Chicago Police Superintendent Garry McCarthy stands near guns confiscated in Chicago and talks about the department's efforts to curb gun violence during a news conference in Chicago.

McCarthy calls a requirement that people go through only 16 hours of training before they are issued a concealed carry permit "Incredibly troubling." (AP Photo/Charles Rex Arbogast, File)
