i think there is a difference between having the urge and the actual ability to do so and decision to act upon it. can you control the urge? we all have thoughts, good and bad. are you planning on acting upon it is the question. i dont think he can lock you up for your thoughts, it is only if he believes you are going to act upon it and he has a duty to protect the people you want to harm. tarasoff is the law. he has to warn the people you are wanting to harm and the police. but if he believes its only a thought you are not going to act up he does not have to report. people say they want to hurt people every day and they are not getting locked up.
