With all due respect to Mrs. Bernhardt, you do not involve the police unless it's to report evidence of a crime having been committed or unless there is an ongoing or imminent threat of a crime being committed.  If there is a suspected mental health issue and it has not risen to that level, then there are better, less provocative and more prudent options to consider.  Police officers are not mental health professionals, are not your family doctor, your priest, your close family members or your best friend.  Just as you wouldn't call an electrician to fix your plumbing woes, neither is it in anyone's best interest to attract the attention of police unless it's to respond to something they are trained to handle.
