Here's my witness testimony from when Zensras messaged me on Discord about it:
"Well I was an event character with a bunch of other people. I was told by a staff member who was spectating other people while on the event character and I remember him saying "There's someone cloaked and no clipped flying behind us." He said the same thing a few times, and suddenly he announced the he was behind me, Commando Droid 1077 and the person behind me was a 41st Green Company trooper. What surprised me is that he was able to get behind us so early in the event. We had the whole area on lock down and it's kind of odd he got back there. Also among that the same person reported came back and said "I was going to knife you, but it turns out I actually can't." Him being just a clone I killed him instantly and then I continued on with the event."
Since I'm the evidence I think I should hold myself from doing a +1 or a -1.
EDIT:
However for the first encounter with the Green Company Trooper @Sock Monkey did also see him and I'm not 100% sure if @Quill Khan also. Perhaps more witnesses are required, and these two are possible witnesses.
Also for the 2nd paragraph, the accused is alleged and innocent until proven guilty despite what I said. It was just a brief confirmation what I believe happened.
