This is just my opinion. I haven't done any research.

In my state, it takes exactly six months of (fairly rigorous) training to become an EMT, though advanced training takes a little longer, and experience in the field would obviously increase one's body of knowledge. Even so, I wouldn't think that an EMT has any more authority than the average citizen to "commit" someone to a psych hospital. It would more likely reflect on HIS credibility to make accusations about another person's suitability for psych admission, especially a family member with whom he has a contentious relationship. He would look utterly ridiculous, IMO. It would take less than a five-minute interview for a physician to realize the truth. This man is overestimating the value of his position in the medical hierarchy. I don't mean to offend any EMTs on this site, BTW...I appreciate your service and know you save lives as first responders.

I believe that in the 1800s and early 1900s, a husband could have his wife committed (or at least divorce her) for burning the toast at breakfast, but the laws have changed.
