In some States it's extremely difficult to involuntarily detain someone for mental illness. They have to have a plan to die by suicide or threaten to harm someone. If they don't admit it to crisis response person or police, the police have to see the pills in their hands as they are about to take it or the knife in their hand as they are about to harm someone. It's like that in Washington State for example; and minors 13 years of age and older have the same rights as adults. So parents can't make them go to counseling or take their medication unless there is a difficult to get court order. I know people who have had to deal with this.
