Abstract
U.S. police deal with nearly 600,000 violent crimesÑmurders, rapes, robberies, and aggravated assaultsÑa year. More than 1,500 officers are assaulted annually, with some 50 killed in the line of duty, according to Justice Department figures. How do the men and women in blue remain mentally healthy themselves, even as they face danger and apply psychological principles in their work?
