The biggest complaint was that spouses would be able to track their SO when they suspect cheating. I suspect said complaints came from said cheaters. In reality, it is the troops who face danger here. Granted, one would have to know the facebook username of a soldier to make use of the information, but how often are soldiers alone? How many profiles list their divisions? It wouldn't take much to track down an entire detachment. Last I heard, you still can't disable that feature. My Linux mini is in the bedroom. It doesn't have GPS, but I'm not at war.

All we're waiting for is the body count to get high enough. We sure as hell didn't need either one of them twenty years ago.
