Look, honestly most cops have better things to do than arrest a person walking home from a bar and not bothering anyone. Yeah public intoxication is a thing and there are a few dick cops who will, but for the most part you don't have to worry about it. The cops around here don't arrest for public intox or even weed possession anymore because they know it will get bargained down to a fine and maybe court supervision (though if you are causing other problems or being an asshole they might). This is firsthand from a local cop. They just have a lot more serious things to worry about.
