This whole thing is BS! The homeless I run into want outa jail just as much as everybody else! This old guy is going to find out losing your freedom is far WORSE than dying of cancer! If you've never experienced hearing that door slam, you don't have any idea what you're talking about. It sounds like someone slaming the lid on your tomb!
There are countless programs this guy could look to for help. Jail is NOT an answer. All he had to do was contact his local hospice to get help. I sure hope the degenerates that prey on people like this will leave him alone, but the odds are slim to none!
