The Torygraph may have the correct story and Stupot may have admitted that the events were as described. What would seem evident, in that evidence is being given, is that he did not admit the charge.
I do not recall seeing exactly what he was charged with but as the offence being discussed seems to be a criminal offence but the court is a military one, maybe we are all barking up the wrong tree.
Sorry, forgot, it was a ground floor window.
