Thanks, I updated my comment. I meant that due to the comparatively low number of aggressors, most people aren't on the receiving end of common assault. At least, not assaults serious enough to worry about. (Poking is also assault, if unwanted) To clarify, in high crime jurisdictions, lack of prosecution for common assault or petty robbery actually does become a societal problem. It's still not the case that most people commit crimes, but enough do that all people worry about it. In most parts of North America, crime has dropped enough that common assault and muggings aren't realistic worries for most people, most of the time. Sexual assault is still done by enough people that all women have to worry about it on a regular basis. So I think the distinction depends on how many people commit the offense, which affects the percentage of the relevant population which is a victim of the offense or realistically has to worry about it.
