I have to wonder how something like this happens. Does a family member (or an enemy?) simply show up with a lawyer and request a commitment hearing? What kind of "proof" could they present to convince any court to commit someone, without the court even considering hearing the other side of the case?
Not having the details (and not wanting to wade through a 100page legal brief, where I might not find the answers anyway), it would appear that the mans rights were violated because proper due process was not followed, not because he wasn't crazy.
Obviously there is a backstory to this that I don't have access to, which makes me wonder just how such a situation could come about in the first place.
All else being equal (and it almost never is) bigger bullets tend to work better.
