What a ludicrous thread. Let me see if I can unravel what you're trying to say:
KR restrains your alleged friends.
Your alleged friends ask to be RUN OVER in order to escape jail (but why? This is madness - you know we don't automatically revoke rebel membership in jail here, right?)
You then oblige and kill these idiots, and get banned for VDM.
Sounds like a fair deal to me. You were VDM, even if you had the 'permission' of your so-called friends. For a start, it's a pretty 'non-serious' thing for them to ask for, in terms of roleplay. There's also the question - did you kill anyone else, or the cops involved? And did you give the cops (or anyone nearby) that you were about to run them over if they didn't free your alleged friends?
If you can't get the 'friends' to corroborate your story, you'll have trouble convincing anyone that this wasn't just a lunatic VDM action without any attempt to RP a way out for them. Even if they do say this is true, you're still going to have to face that it was a lame, stupid thing to RP, and not at all realistic or believeable, really.
KillerRabbit made the ban, so it will be his call in the end - but I for one would be letting you sweat it out until I heard something from you that showed you understood what a totally FUCKTARD sort of thing it was that you did.
