From my point of view, the main reason you're supposed to kill someone in this gamemode is to get rid of the traitors. Why would an innocent have any reason to kill a detective? Unless if the detective is metagaming and doing whatever they want, they're only there to help out the innocent. Besides, once you're finally able to shoot after getting tased, it is most likely that the event has already calmed down, whether or not you were killed whilst being tased. Like, if a detective has been targeting a single person or killing for no other reason, then yeah it's fine to eliminate the threat. If you were being tased for a traitorous act or suspicion, shooting the detective in self-defense isn't going to help your case, no matter your role. Besides, it's not like reports aren't a thing.
