None of those screenshots prove that it was the player you've mentioned.
If you have more screenshots please provide them, I will look at the logs but that may take some time.
After checking the logs it seems that he was trying to move away your car so he could take back his spike strip back and your car was over the point where he could access it. As seen in the picture as well as proven in the chat logs.

I am not quite sure on the reasoning behind on why you've killed him right after he said that but since I don't have any solid evidence that it was random death much I'll ignore it.
However, after checking the logs I can see that you are the one who broke the rules. You disrespected players in the OOC chat the same reasons on why you were banned a day ago.

Which translates to Properly Disabled which is disrespectful.

So as far as this player report goes it is denied but the real rule-breaker here is you. You will be issued a 3 day ban for a second offence of player disrespect in the OOC chat.
