No, they don’t.
I stand corrected ( well, self-corrected, since you didn’t elucidate). It appears that the current research indicates that constrictors kill by over-pressuring the circulatory system, killing by ischemic failure of major organs like the brain, live, and heart ( the heart cannot over come the high blood pressure caused by constriction and therefore often goes into arrest with minutes). Broken bones (ribs) may occur in larger animals, but are usually not seen n large numbers nor by intent based on autopsy.
My B-I-L, when a young missionary in Brazil & Paraguay, witnessed the dissection of a snake that had killed/swallowed a man , he said that the guy looked as if he was crushed like a soda can- but certainly there was no autopsy....
