To not get committed, one would have to lie about hurting oneself (which might not have been possible in this case given the visible injury). Not foolproof, but to not get committed, one should keep these thoughts to oneself. Even a trusted doctor is likely to commit one. This decision still lies purely with the doctor. The _only_ surefire way to not get committed is to not see anyone who doesn't have your best interests in mind and that includes all medical and social professions. Sad indeed.
