DeKalb County Public Safety Director Cedric Alexander and police leaders from across the country attended a panel discussion Thursday with President Barack Obama about criminal justice reform.

Alexander is one of more than 130 police chiefs, prosecutors and sheriffs who have started a group called Law Enforcement Leaders to Reduce Crime and Incarceration, whose members attended the panel discussion in Washington.

The group’s goals are to end unnecessary incarceration, find alternatives to arrest and end mandatory minimum prison sentences.
