March 15, 2010 | Adam Sorensen | Leave a comment Throughout America’s history, there have been thousands of criminals. The Pew Research Center reported that in 2008, there were 2.3 million individuals behind bars.And then in 2009 approximately one in 31 U.S. adults were behind bars or on probation. From America's beginnings as a dumping ground for England's criminals, individuals who defy the law have flourished in this country. With this heritage for crime, the U.S. has learned to rely on a strong police force. Today, thousands of officers and other law enforcement officials make their careers keeping U.S. citizens safe from criminal threats. To celebrate these law enforcement professionals, we've compiled a lift of America's 7 Worst Criminals of all time, courtesy of ClassesandCareers.com, a free career information service: 1.
