Not sure I am with you on that. Scotland loves scandal! Also his case was decided almost as we entered into lockdown so that would have held up things. He would also have to find a new lawyer!!! Said lawyer would have to weigh the material produced by Salmond against that put forward at the trial and make the case of collusion etc from that. This all takes time. To go at it head on would have seen errors and weaken Salmond's case. It also gives more time to drip feed scandal into the media, see the bits about Nicola not informing/misleading Parliament.TBH, to create any lasting impression on anyone other than his die-hard supporters he should have gone for the throat immediately his court case ended in his favour. For all those outside his immediate circle I strongly suspect he will be seen at best as irrelevant and at worst a very bitter man.
No to have gone bull headed from day one would have been a mistake and Wee Eck is nothing if not an astute political animal.
