So you're suggesting she thought 'I know what'll get me in the papers! I'll dig out a picture that was taken a few months ago - one that'll really offend some people the other side of the Atlantic and post it on Twitter - and at the same time I'll make the whole of the UK hate me'.
She did a truly stupid thing! That is all she is guilty of. Frigging hell - if we executed everyone for doing stupid things - we'd all be dead by now!
Yes,I think that is what she thought exactly.
I don't think anyone asked for her to be executed,that would indeed be over reaction.
She is getting discussed, and behind the facade of "mea culpa" she is no doubt satisfied.
