U.S. Senators Claire McCaskill and Kirsten Gillibrand have long championed competing bills to change the way the military prosecutes sexual assault cases. The Senate voted this week to approve the McCaskill bill. It offers modest reforms but still allows military commanders to decide whether their subordinates should be prosecuted. The vote disappointed the Gillibrand camp by not removing the chain of command from military sexual assault cases. The Pentagon itself has indicated how serious the issue is: more than 20,000 incidents of sexual assault and unwanted sexual conduct were reported in 2012.
