I thought the reason why their bodies fell apart when the water hit them ,was because the zombies were starting to deteriorate now that two years have gone by. A normal human hit by a high powered fire hose will get red welts and bloody bruises from it. That is why we weren't allowed to use them on inmates in ad.seg., to make the inmates who refused to shower, a good cleaning. The inmates ended up in medical getting an exam and treatment and we had to fill out a use of force report if they did use them. This was years ago when I first started in the Texas prison system in 93.
