I was there so guess i'll have to leave a reply here
As mentioned above, only an RA+ can give permission for prisoner execution, if not then RC can do it, however this does not mean RC can give permission to others iirc.
You did infact RPG the explosive tanks that were placed below me, yes you did tell people to leave but you still shot anyways, it's common sense to wait til everyone is out first to shoot, that is if you had permission from an RA in the first place.
You killed alotta people so yeah it was a justified ban
Also one thing that i hate about this thread is the fact you mentioned people with you and a video that didn't include evidence aswell as people in it, honestly seems like you wanted to get people in shit with you imo
