So far as I know double jeopardy comes into play when you are found not guilty. In that situation the prosecuter cannot go back to the drawing board to put a better case together and retry you. Someone found guilty can always appeal the verdict and hope to eventually be found not guilty.
There are probably some differences between civilian and military trials but there are others here more knowledgeable about that.
That's what I was wondering - do civilian and military trials overlap.
Do they have equal status?
Do they have pissing matches over who is number one in charge?
