Both of those things can be sexual assault and often are. Just because we have allowed men to get away with this sort of sexual crime in the past doesn't mean it isn't a crime. Accidental touching obviously isn't a crime of course.Obviously counting a leg or arm touch over clothes as sexual assault is nonsense, unwanted or not, but clearly there's a pattern there of perhaps someone getting gropey and forcing himself on women when he's been drinking. It's the attempted rape charges that are where the focus will be. The rest is presumably just to help paint a pattern of behaviour to a jury. His reputation is destroyed whatever the outcome, he always was the perfect stereotype of a sleazeball.
Even now a single unwelome touch over clothes will rarely result in charges.
