Folks, there are very good reasons why a body isn't shown to loved ones.

47. You may be right. She could have been dangerously traumatized.

However, as a functioning adult, that's her decision. She's already been traumatized and not knowing is making it worse.

Let's turn this around. Let's say Sgt Johnson's nearest NOK had been an adult male - brother, son, father. Making it even more interesting, let's say that man was suffering from combat PTSD and had been through this on the battle field. Would he have been denied the right to see the body or is this "Let's protect the pregnant woman because they're "sacred", emotional and fragile?

Finally, is there a law, a statue, an executive order that allows the Army to deny a civilian NOK to see a body, no matter what condition it may be in? Mrs Johnson isn't in the service; she's not a federal employee. She's a private citizen. Yeah, when a service member is alive, s/he can be and often will be told to keep their mouths shut about everything. However, Sgt Johnson isn't in the Army anymore; he belongs to his family now.
