I was making no assumptions, I for one am for sure not a Glock fan, but the story at the link doesnt mention Glock and the picture at the link is a Beretta. it is an evidence photo as you can see the ruler at the top edge. That does not guarantee that it was the gun used, as Brit journalists are likely to take whatever license they deem necessary to fill a story.
Was Hitlery there?
It sure appears to be blood spatters on it as well.
