To me at least, I don't see memorials for individual soldiers as the right thing for the government to do. Many, many soldiers have died couragious, heroic or unfair deaths and they are memorialised together, as they should be, as is the spirit of the armed forces. Making them for individuals leads down a pretty strange path imo. Same goes for murder victims, which is essentially what he is.
Not wanting a publicly funded memorial for him isn't condoning what happened to him, or any of the bollocks that people will try and throw at people for having the perfectly reasonable opinion that opposes theirs. If people want to fund a memorial, then that's fine, it's their money they can do what they want with it, but I don't think the government or councils should be doing it.
