Yeah, while I still think she whipped up something as a false blanket to keep her in the running, Piers Morgan does indeed have no right to talk about respect and morals.
Essentially, for anyone with even a remote interest in politics and political journalism in Britain by that point, Piers Morgan was deemed a filthy snake. If anything you may have heard about the Rupert Murdoch 'News Of The World' phone hacking kerfuffle and the subsequent inquiry into it by Lord Leveson (Aptly named the "Leveson Inquiry"). Piers had already been lynched over to the US at that point, but he was still very recently involved in this.
Essentially, he allied himself with Murdoch and tried to skirt around any absolutes in order to avoid saying anything that would directly implicate himself, Murdoch, or any of the others involved. His whole testimony was ridiculous, he was not taking the situation half as seriously as he needed to, and while admitting to hearing recorded messages, still denied any absolute knowledge of phone hacking having occurred. There are even allegations that he has published certain articles that were knowingly sourced directly from the phone hacking operation.
I mean he's done plenty more than that too, his controversy spans pretty far and wide. At one point he was the judge of our talent show, and I'm sure if anyone has watched yours over there when he was judging that, you'll have a pretty strong idea of why those disinterested in politics also dislike him. He's pompous and he has no distinct level of empathy for anyone, his ego is incredible and his morals have all but been dusted away under the rug.
I do loathe Piers Morgan, but I still can't help but see that lady's response as somewhat of a cop-out.
