I think the article does, to some extent, address this when it says that the situations that we would most hope for modification in police behaviour are also likely to be the situations where the officer is under significant stress and has defaulted to their most primal response. So while I take your point that police don't think they are doing anything wrong when they misbehave, I think it is more correct to say that police aren't considering moderating their behaviour when they are in those particular situations.
