A problematic entry in the continuing series

A loyal reader points me to this bizarre story in which a Kentucky man is claiming caffeine intoxication as a defense against murder. Apparently there is some (but slim) precedent for this.

Counterpoint: he's claiming that his caffeine sources were "sodas, energy drinks and diet pills." I've never endorsed energy drinks or diet pills, and distrust the thought that caffeine is the only relevant ingredient in them.

Counter-counterpoint: "Reports and case records say that during that time, he was drinking five or six soft drinks and energy drinks a day, along with taking diet pills; it all added up to more than 400 milligrams of caffeine daily. The Diagnostic and Statistical Manual of Mental Disorders — the American Psychiatric Association's guidebook for the classification of mental disorders — defines a caffeine overdose as more than 300 mg."

If 400 mg of caffeine provides a legal defense against a murder charge, then I've been entitled to at least two, usually three kills a day for years now. I'm starting my list for this afternoon right now.
