Ever heard of the My Lai incident? Be more careful not to mention things that can be turned against you.
http://www.encyclopedia.com/html/M/MyL1aiinc.asp "In the course of combat operations, unarmed civilians, including women and children, were shot to death (the final army estimate for the number killed was 347). The incident remained unknown to the American public until the autumn of 1969, when a series of letters by a former soldier to government officials forced the army to take action. Several soldiers and veterans were charged with murder, and a number of officers were accused of dereliction of duty for covering up the incident. Special investigations by the U.S. army and the House of Representatives concluded that a massacre had in fact taken place."
