@Amber:  Good point!  While we don't know the details of this crash, and thankfully both the deputy and the trooper sustained only non life-threatening injuries, statistics show that increasing numbers of officers are tragically losing their lives while driving patrol cars.  Experts say the increasing amount of in-car technology could be a factor.   NHTSA did a research study in January 2011, "Characteristics of Law Enforcement Officers' Fatalities in Motor Vehicle Crashes."  There's some fascinating info here:  For example, in 1999, 2003, 2006, and 2008, over half of all LEOKA fatalities were officers killed in law enforcement vehicle crashes. In 2013, the number of officer deaths resulting from law enforcement vehicle crashes was exactly equal to the number of officers feloniously killed (27).   Law enforcement is a dangerous job, and technology should be protecting officers, not endangering them.
