This is where I don't agree with some of the al-anon advice. We're not suppose to get angry when our A's mess up, we're not suppose to bring it up or yell about it. But if I don't do or say anything, then he feels he's getting off without a hitch, scott free so it happens over and over.
Getting angry doesn't help either of you. AlAnon advice is for you. getting angry doesn't do you any good.
Now the letting him off scott free? That is where boundaries come into play.
Setting them and enforcing them. You can set boundaries all day long, if they are not enforced... he would get off scott free. The police are not holding the boundaries that the law has set. Are you holding the boundaries you have set?
Look over the steps. See what you can do for you. Keep yourself in the correct emotional level you need to be and evaluate your set boundaries you have for his behavior.
