The Psychiatrist is under a legal obligation to maintain that privilege under virtually ALL circumstances. However if he honestly thinks that his client has told him of an intent to commit a crime, eg. Murder.
Then he is obligated to tell the police.
this only applies if they tell you they ARE GOING TO commit a crime.
if they are telling you of a crime they have committed i do not think they need to tell the police. they only need to tell the police if they are an imminent threat to themselves or others.
a doctor would not need to tell anyone if they are simply telling them of crimes they have committed. actually, airing past crimes to therapists is common and necessary for effective treatment.
i do not tell the police anything. I would not tell them if i knew my mother would go on a killing spree.
they are,in a lot of cases, the biggest and worst gang. they hide under the veil of legitimacy.
how much drugs and money go missing from evidence lockers? lots
the police have no compassion. a few years ago they released a homeless man out of the drunk tank. they dropped him off at a corner in below freezing temp. he froze to death.
the police are currently on a tazer spree. a few years ago they killed a man in the airport in my ciry. it was all over the news.
also, let the police try and prove that you knew about such things. knowledge is hard to prove. it is in most cases his word against yours. him being a criminal, in most cases.
