That sort of thing generally shouldn’t make a difference in the U.K. But in this case I think the law gives special protection to public figures and I guess people who are knighted tend to be public figures. It used to be the case that peers (ie lords) had a somewhat different treatment in the law: they would be tried for crimes in the House of Lords instead of a regular court. The idea of that seems more reasonable the further back in time you go as the nobility had more power. However that is not the case anymore either. It continues to be the case that the justice system is more accessible to some people than others and having better access likely correlates with the probability that one is knighted.
