You guys are making this more complicated and overwhelming for a simple rule we want to enforce.Â

It's simple don't reactivate situations that are over and done with. For example if a shootout ends between police and players at the KFC and EMS are starting to revive people and heal them that should be the end of it. A car with 2-4 players shouldn't show up after the situation has ended and reactivate the situation STARTING another gunfight. This isn't role-playing, it makes it seem like a DarkRP with this happening over and over again.

Q&A
Q: Your friend's house getting raided?
A: Yes you can still help them

Q: Can I rob a gas station with all my gang/friends?
A: Sure go right ahead just make sure everyone is in OR at the place of the robbery before starting and stay within the role-play zone.

Q: All of my friends/gang members died and are now being arrested, can I pull out my weapon and tell the police to let them go?
A: No, you should have been there at the beginning of the situation. Don't interfere, don't cause a new RDM Fest. Role-play it out. You can break them out of jail AFTER they've been processed in.

Q: My friends/gang members are being mugged, can I show up and then pull out my weapon and tell them to stop or just shoot them?
A: No, again, you should have been there at the start of the situation. Only help your friends/gang members if you are there when the situation has started.
