Jack Papp has succeeded Anthony Guglielmi as PA director of the Baltimore Police Department, which has been battling a spike in violent crime.

He's a 20-year plus veteran of the U.S. Navy's PA office, San Diego County Water Authority, American Red Cross -- following the aftermath of Hurricane Katrina -- Lockheed Martin and Altegrity, global security consulting.

Eric Kowalczyk, acting PD spokesman in Charm City, has been promoted to lieutenant.

Maryland governor Martin O’Malley, a possible contender for the Democratic nomination for president, and Baltimore mayor Stephanie Rawlings-Blake are feuding about police tactics of fighting crime in the city.

O'Malley wants more arrests, saying Baltimore can’t revert to the "pathology of failure." He told Fox45: "We can't fall back into the pathology that led Baltimore to being the most violent and addicted city in America and all of us shrug our shoulders while lives are lost, children are being shot, people are being sprayed with gunfire in broad daylight and go back to the old Baltimore pathology that says there is nothing we can do about it."

Blake believes it’s inaccurate to "suggest more arrests leads to less crime, opting instead to focus on the most serious offenses."

Former New York and Los Angeles police chief Bill Bratton is advising Baltimore’s police department.
