Hello Brandon,
After talking with the banning Admin and having lots on experience with you on server I have decided to Deny this appeal.The reason for this is that I feel personally you have had enough time and Bans to understand the rules and this point and not make mistakes as big as this. You Appeal your ban nearly every time so you clearly want to play the server. The detective was likely placing the C4 to get DNA on it. As far as why you were banned in the long term you have multiple recent bans so after you were unbanned you got 4 recents within 2 days leading to another ban. Your warns are for more than just RDM as well so you should give the rules a read over while you are banned. You can read them Here.

I do wish to see you come back with a better knowledge of the rules.
