I had to commit my husband to a mental institution three times during an eight year period due to his traumatic brain injury and bipolar disorder. Anyone who has ever had to do that knows just how wrenching the experience is not to mention frustrating. It is hard enough to make the decision to commit a loved one and that is when you learn in most states the amount of time a person can be committed is short of the 21 days it takes for the medicines they refuse to take really begin to make a difference. In the United States the approval to commit someone is made by a judge who in most cases knows nothing about mental illness. That is not the case in other countries where medical personnel make that decision.
