I will post screenshots of what I saw and how I personally interpreted the situation, basically you went up to blue door with a single Security guard while an imminent raid was inbound, Nu-7 told you to literally move back not only because they didn't want you to go to the surface but also for your own safety. You opened blue door which got several Nu-7's killed in the process and even almost yourself. What I personally don't understand is why you were laughing during the incident, you went back into Gate-A but instead of retreating you were simply watching the raid happening a good five-metres in front of you. As a Site Director you are supposed to value your own life especially as the highest ranking member on. While I do believe arresting you wouldn't of been the way to go about it I do not believe that stripping his WL was the necessary thing to do also, Shin Dowa is an actual good Nu-7 unit and he's an NCO for a reason.
Merely my opinion and perspective of this
