Just to clarify: I wrote, "A couple of reports said that Z.'s carrying of a gun had been a source of some contention within the neighbourhood watch" - I should have said "contention between Z. and the rest of the neighbourhood watch." I clearly remember one article that said he had been kicked out of the neighbourhood watch over this gun issue, and so that he could not have been 'officially' on duty at the time of the incident. However, there has been so much misinformation, and slanted and exaggerated information, whether in support of one side or the other or just to have another story, that it's hard to know what the truth is. It's curious that some of these apparent 'facts' have quietly disappeared from subsequent reports. No doubt the trial will be enlightening.
