Travesty or not, it is typical of an "investigation" in the military. In the military, you are investigated by an officer with absolutely no experience or ability to lead an investigation. It is a O-1 thru O-3 who was so fucking stupid he could not get out of this extra duty. About 99% of the time they are told what their conclusion will be before hand and they find it as ordered.
Search warrants are signed by your commanding officer, there is no judicial process and no real oversight until your conviction goes to the U.S. Court of Appeals. If the military appoints you a lawyer, it is the stupidest fucking idiot ever to pass a law school graduation. Inept lawyers are assigned to the Area Defense Council (ADC), they defend the accused. If they are to go at their job, they switch them to the Judge Advocate General (JAG) and they prosecute you.
You have to privacy with a military lawyer and no confidentiality. If you admit anything to your military appointed lawyer, he reports it to the JAG and they use it against you. No one in their military system is trustworthy. Under the UCMJ, you can get tried and retired until they fabricate a conviction.
It is not surprising that they would do this and ruin careers and lives over complete bullshit. This is probably seen as a first rate, top notch investigation by the Army.
