Perhaps, I was uncharitable in reading your comment. To me it is unsurprising that we don't know exactly how it went down. Based on published quotes, Kim Jong-Nam, himself, did not know exactly what happened. It just struck me as an odd detail to call out. I wish I could expect better of journalists, but I find many news sources will publish any random speculation, and therefore, there are many that I either avoid or take with a very large grain of salt. As you highlight, the BBC is one of the better ones.
