That may be so but unfortunately that's not going to happen anytime soon. If anything the mental health system has become more and more broken and IMO no longer provides troubled youth the treatment that may very well rehabilitate them. Budget cuts and dwindling numbers of available hospital beds have led to institutions keeping patients for shorter amounts of time, nowhere near what would be needed for adequate treatment.
In 1983 an adopted 12-year-old boy, Kenny White, lived a few blocks away from me in Kendall Florida. One day he shot his mother and brother. Miami authorities decided to provide him with intense, long-term treatment at a private mental health facility, St. Albans, in Virginia. Here is his story (the articles are long):

A total of $600,000 was spent on Kenny's treatment at a time when the average budget per youthful offender was about $13,000. As of 1999 Kenny seems to have graduated college, found employment and has stayed out of jail, making his story a success.
However, it's impossible to repeat what authorities did for Kenny today. That $600,000 is more like $1,484,213 in today's money. And the 162-bed St. Albans has been closed and abandoned. In it's place is a new 36-bed mental health clinic.
Currently there just aren't many options for troubled kids and so until the juvenile system is revamped, with more funds and hospital beds available, I'm afraid the alternative is to keep these kids in detention for as long as possible to protect society and try to provide them with at least some sort of therapy. It may not be the best solution or even the right solution but I don't see anything better.
