Burt was right
Reading through the reviews of this film, from big-name critics as well as ordinary Joes, I noticed most criticize the character of Maddox as too rigid, a mere killer, etc, causing a great deal of harm by a too rigid adherence to the law. After all, the arguments go, the killing was accidental, these were good men, Sabbath was a peaceful town, etc. I can't agree with any of this.
1. They not only shot up a town, they set fire to buildings, destroyed property, and killed a man. Their claim is the killing was an accident, but is it an accident if you fire a gun into buildings with people all about. At best, that is not exactly an accident. Actually, because they were committing felonies (arson), under American law I think it was first-degree murder. But there is a second issue--declaring this an accident is simply pre-judging the case. How do you know one of these men didn't deliberately shoot the old man? That is what a trial decides.
2. All Burt Lancaster wanted to do was take them back to stand trial. After what they did, they all should have gone back.
3. One by one, these men tried to kill a law enforcement officer who was merely doing his duty, either by forcing a shootout (Salmi) or by outright drygulching (Waite and Duvall, the final shootout).
4. The rich rancher admits he is going to bribe public officials and corrupt the legal process, as he has done by buying the local sheriff.
5. The local sheriff does not do his duty, and is on the take to the rancher.
6. Maddox is a breath of fresh air in this putrid town, which is corrupt to the guts. My only real criticism of Maddox is that he buckled and went "bleeding heart" at the end. The guys who got killed at the climax would have gotten away with it if they had just been smart enough to let him ride off without trying to backshoot him.
7. And what about J D Cannon? Well, this is the best argument against Maddox, but he was fleeing arrest and had just taken part in and drawn a gun on Maddox in a shootout. As for the "backshooting" argument, there is a distinction between shooting a brave man in the back because you don't have the sand to face him and having to shoot a coward in the back because he turns his back and runs after trying to kill you.
