WASHINGTON (AP) — The number of law enforcement officers who died performing their duties in the U.S. declined by about 20 percent in 2012 after rising the two previous years, a non-profit organization reported Thursday.

The National Law Enforcement Officers Memorial Fund said in a report that 127 federal, state and local officers have died so far from injuries suffered on the job. The majority of officers who died were either shot or were victims of traffic accidents, figures show.
