Stanton, your opinion means nothing to me. You are entitled to it.
I don't know the background of Lawman, whether Winner was part of the development of the film, or if he was hired on, or if he read a script and decided he wanted to direct it. But he is credited with producing, which indicates involvement early on. I like Winner's films from the early 1970s despite his sloppy, zoom-happy direction. For me, the success of the film is in the writing. The script is exceptional. And in the casting. Thematically it is very much a product of the 1970s, but its underlying themes are relevant today.
Not many, but you should try living in my neighborhood in Arizona where extreme law enforcement with a touch of meanness, if not sadism, is the order of the day. Even the traffic court is "in" on it. Even my uncle, a lawman in the state for forty years who retired 17 years ago, has been victimized by the newer cops who don't know who he is. The fact that he started the Policeman's Association (which helps officers injured on duty, and with other troubles) means nothing. A private citizen is nothing more than a source of revenue to the police dept. You'll find this attitude has spread all over the U.S.
