Gir and vic go back and forth for a while and eventually vic gets tired of Gir ignoring him so he starts to shoot the bag and Gir knocks him out and meles him. He didn't just knock him out like the vic did to the mafia, he knocked him out and killed him. He didn't question the mafia (who was alive in the bag) about what happened, he just let him out. The mafia killed him without hesitation. That is RDM.
It's not RDM, it's you trying to make it look like it. Quit trying to warp things into your favor. You made a bad call, get over it. There's no reason to continue this bullstuff.
Simply explained, in any case:
Victim shoots the bag, Gir knocks him out because he thinks he's trying to get away with killing who he thinks is an inno.
Albeit it was a bad call to kill the vic, but I guess that's just instinct.
He probably should have questioned the maf before letting him out, but, considering what he's said previously
He had not witnessed the mafia member do anything suspicious, therefore there was no reason to suspect him. It doesn't matter if it's false or not.
I don't think he realized the bodybagged guy was actually maf.
