False complaints of sexual abuse in the military are rising at a faster rate than overall reports of sexual assault, a trend that could harm combat readiness, analysts say. Virtually all media attention on a Pentagon report last week focused on an increase in service members’ claims of sexual abuse in an anonymous survey, but unmentioned were statistics showing that a significant percentage of such actually investigated cases were baseless. From 2009 to 2012, the number of sexual abuse reports rose from 3,244 to 3,374 — a 4 percent increase.
