Unequivocally, yes I would. I work with people who have severe psychiatric disorders pretty regularly. The difference between someone who is untreated vs. someone who is stable and adherent to their med regimen can be light years.
Part of the reason we fear people with psychiatric disorders so much is because we, as a society, fail these people. We have no reliable system for remanding them to get help, if we see signs they are decompensating. The only system we provide is one that only starts to function when they've reached crisis level.
That's not their fault; it's ours. They deserve better. A better system could have prevented this crime.
Most likely he's on Medicaid. He's going to a group home on a monitoring program and missing doses because he couldn't afford them would be a probation violation. I don't know the exact details, but I'm willing to bet that's how they have it structured.
