Paramontana said something in TS saying that if a staff is in the middle of the street handling a sit and they're wanted then you're allowed to arrest them or kill them if they have a hit. I believe this is basically the same as that. I don't agree with your warning and even if Sorle just TPed as you entered or whatever to start the sit then I don't think you should have been warned maybe just PMed saying it was a sit or something then they can continue the sit on a roof.
