Miller v. Florida

John Miller (defendant), seeking treatment for heroin addiction, was sedated and given intense doses of several toxic drugs at a clinic to speed his withdrawal, then released after 27 hours while still heavily sedated. Within three hours, he returned to the (different, closed) methadone clinic, shot the lock off its gate, wandered the grounds firing at the building, broke a window, climbed inside, and eventually surrendered. Florida charged Miller with shooting into a building, armed burglary, and discharging a firearm in public; he raised insanity and involuntary-intoxication defenses, but the trial court rejected his proposed involuntary-intoxication instruction and gave a substitute instruction that misstated the law, after which the jury convicted him.
