The number of ambush attacks against law enforcement remains steady – with about 200 a year – but more police are getting killed as a result, a Justice Department study found.
The study examined surprise attacks between 1990 to 2013 and concluded that there is reason for alarm and that “officers must not only be guardians of the public but also be prepared to respond to violence targeting them,” The Washington Post reports. 
“As part of our work to support these brave men and women, the Department of Justice is committed to extensive efforts aimed at preventing violent action against the police,” Lynch said in a statement. “This report will serve as a critical base of knowledge as we work to defend our law enforcement and ensure our officers’ safety.”
One deterrent, the study found, was in-car cameras.
