Or it could have been a hunting rifle the shooter felt was so old it would be untraceable. Non-shooters are the web are going nuts over the 200 yard distance but I don't think that's an unreasonable distance for a hunter. It wouldn't even surprise me if the shooter was going for a head shot and got Kirk in the jugular by mistake.
Meanwhile, the Leftists that realize they can't openly celebrate this are saying, "but what about the Minnesota couple gunned down in their home?" or "but what about the school shooting the same day?"
No need to stoop to their level. Kirk's assassination brings to mind Obi-Wan telling Vader that he'll just be stronger than ever.
