It is standard practice in disciplinary cases to get screenshots of evidence, precisely because it may be deleted. Are you seriously saying that in this case, despite lots of people seing it and being affronted, and despite the coaching of the Israeli Ambassador in how to make complaints, no-one managed to grab a screenshot? Seriously? No, you really can't be serious.
My point is that selection panels will select who they wish, and bar who they wish, and sometimes they do so on partisan lines. Camden does not operate differently to the rest of the Labour Party afaik. I know little of Camden LP (do you?) but I've seen LP selection panels operate (have you?).
This makes no sense.
Neither does this.
