I think it also depends on from when some of the inappropriate behaviour he's admitted to is from. I know it's never OK, but you can't really always judge things in today's standards.
I had a boss who would always put his hands on my shoulders when leaning over to see what I was working on, there was nothing in it and I never felt uncomfortable but I could make that into something now.
I've also had people who did nothing and didn't lay a hand on me but made me feel very uncomfortable. I've never met him but I could imagine salmond might make me feel like that.
