I live in Houston and am unfamiliar with this law.
However, what I do know is that the medical profession, and particularly hospitals, have too much legal power. Even if one is admitted to a hospital on someone else’s say so then that patient is, in effect, a prisoner until such time the hospitals and doctors decide if the patient can go home. Any patient who objects and leaves of his own free will then he has left the hospital “AMA, Against Medical Advice!” Translation: ‘”AMA” = We refuse to pay your medical bills’ and you get stuck with the entire tab!
I once called the police to report that I was being held as a captive by a hospital. The copthug showed up and asked the nurse if I was being held against my will. She replied, “ He is a threat to his own life!” He turned and walked away without even asking me any questions! I was a prisoner in that hospital and Big Brother let it happen!
Cops and nurses have a special bond. Just FYI.
