This question only applies necessarily to rooms with 1 door: 1 entrance and exit. Additionally, this situation only applies to the room with no more than 2 people: a traitor and an inno. A good example is Hairyhouse where much of the rooms are dead ends within the house itself. Let's say a Traitor kills someone in one of these rooms and proceeds to leave. As you enter, you see him reloading with the body behind him. Now obviously if it is unided, you can kill him for it. However, what if the body was identified by him? Minus a C4/explosion going off (which you would definitely be aware of), it's obvious the guy exiting the room with the body is a T and he killed the inno. Is it KOSable to kill a guy exiting a 1 door room who is going through the reload animation with an identified body behind him or is it still considered killing on suspicion?
You would need to prove a few things first: 1. Did you know for a fact that they were the only two people in the room? 2. Did you know for a fact that nobody teleported out of the room? 3. Did you know for a fact that the person was killed recently (that meaning, did you hear the shots? Did you check the body to see what time the person died?) 4. Did you check the body to make sure he was killed with the weapon the player was holding? Essentially you would need to see them in the room beforehand to know they were the only two, hear the gunfire and the kill, check the body for the kill time and weapon, and then you could probably achieve 100% certainty. If I can poke a single hole in your logic, than you didn't have 100% certainty when you made the kill. We handle this on a case by case basis most of the time.
