Two Americans go back on trial in Rome over killing of Italian police officer

Highest court threw out previous convictions of Finnegan Lee Elder, 24, and Gabriel Natale-Hjorth, 23,

A new trial has opened for two American men accused of killing an Italian plainclothes police officer during a botched sting operation after Italy's highest court threw out their convictions.

Italy's highest court of cassation ordered a new trial last year, saying it had not been proven beyond reasonable doubt that the defendants, with limited Italian language skills, had understood that they were dealing with Italian police officers when they went to meet an alleged drug dealer in Rome.
