Assuming you were the officer who died in his suit in the video, didn't you obviously break NLR ? It's more than often that users who break NLR get killed by the users who wouldn't like to see another user break NLR.
He DID rulebreak, but so in an answer to you. I don't see why he would be punished for it, a talking to would suffice. Many people take "law into their own hands" regarding this matter.
