Depends on the law enforcement. My aunt would ocassionally get arrested, but they'd never charge her with anything, just bring her to the hospital for an involuntary psych hold, and she'd find her way back home after that. I don't think they ever found meds that worked for her and that she'd take consistently for more than a couple weeks. (This was in San Pedro, CA, which doesn't fit your suggestion of a wealthy suburb)
