He's on so many meds, maybe theyre the wrong ones.

My son has schizoaffective disorder which just means schizophrenic and bi-polar. He is only on risperdal but up until last week he was also on olanzapine. They havn't introduced a mood stabalizer and dont know if they will. We made it clear to the doctors that whenever he has an episode it results in someone getting beat up and recently almost killed someone. Wether he is psychotic or not he is facinated with the army and owning a gun. We recently found a letter from the gun registry denying him firearms due to a background check they did. Just before he went in the hospital he was fixated on going to his dads to get a chainsaw that he "left there" his dad informed us that he didnt leave a chainsaw their that the chainsaw is his. A couple of weeks ago they let him leave the hospital for 2 hours and he went and drank. They up'd his medication and then a week later took one of them completely away. Today without the hospital telling us they let him out by himself again and he drank somewhere then showed up at our house smelling of alcohol very agitated and yelling and screaming and gritting his teeth telling us he has nothing and that his doctor and probation office think he is not schizophrenic and that he can drink. We are terrified in our own home. His father took care of him for 7 years and he turned on his dad one day last April beating him up breaking his nose. He went into the hospital and was released a month later and went back to his dads and threatened to kill him and his wife. Police were called and they had to draw their weapons to calm him down. Once he was released again from the hospital he left the province. He ended up in the hospital and eventually jail their for beating 2 men up and one so serious that they dont know if he will servive. When he was released from jail they sent him home on a bus. He came straight to our home because he had knowhere else to go. He went into an episode right away and we talked him into going to the hospital through very gental persuasion. Over the years he had little contact with me because I am in a same sex relationship. The day we brought him to the hospital he had made a comment that "gays shouldnt breath" He is very angry and able to not show it to the doctors and staff. We dont feel safe anymore everyday we are living in fear that he will kill us. The doctors know all this and have all his records from his visits to the hospital and courts but yet they let him out knowing he probably will succeed and kill someone. Do hospitals actually wait until they do then they get locked up forever?
