Anyone with knowledge of youth justice?

I've only just seen this thread and can't imagine how I missed it.
I didn't get the usual notification on my personal email about your PM lucky girl so I'm glade I happened to check my in box. There has been a lot of media coverage recently about the difficulties families have in obtaining mental health services for young adults who aren't yet old enough to access adult services. It isn't, of course, any better once they reach 18 and are old enough to access adult services.
A close friend took his 20 year old son to AandE. He'd already spoken to the psychiatric ward who know his son and my friend very well. The ward told him he'd have to present at AandE but that they'd arrange for the young man to be admitted as soon as he arrived.
This didn't happen and my friend was 3 hours in the middle of a busy Friday night, in A and E. His son was having a psychotic episode and had been drinking and taking drugs. He was paranoid and his behaviour frightened some people waiting, especially those with young children. My friend pleaded not to have to wait for triage, explained the psychiatric ward knew they were coming, a bed was ready etc, to no effect. Madness isn't it.
