Hi, I was the staff overwatching the PK, approved by Slug. From what I was told the PK was already approved on you and deemed allowed for what you had done, and the only why you'd be able to appeal is on how they killed you.
Sadly, I do not have a clip but what occurred was he was taken from the Cells to the Interrogation room and confronted by the Lapo Chief in this conversation the Lapo chief stated he was going to die, they then transported him in a civilian truck with a civilian car behind it to the outskirts of Berlin near summerhall where he was put on a wall and firing lined by the Landespolizei. In my opinion from what I was told "He' gotta at least rp it out a bit, let him know he's gonna die, etc. If he just runs up and kills him in the cells in 5 seconds he'll be able to pk appeal pretty easily" the PK is valid and has opened up the Lapo chief to get PKed back from the Kaisergarde due to the amount of witnesses that could come forward.
