It's often easier to see the signs after the fact unfortunately. In many cases, people that are in that dark place will often hide it to some extent. I didn't know Scott so I do not know how close he was with family and/or friends. It may very well be he just was not close with anyone to the point they would notice the problems. The legal issues make you think someone would have stood up and noticed, but even then, none of us know if anyone reached out to try and help. In the end, its still up to that individual to accept that help and get better.
