Marijuana Defense?

The RTD reports that the defense attorneys for a 16 year old boy who raped and killed his sister are considering a marijuana defense. Does anybody seriously believe that marijuana would drive someone to kill. More likely it was years of neglect and abuse and a culture of thug violence that laid the foundation for this heinous and inhumane act. Most likely the boy is insane by any definition of the word and was already a victim a tragedy before this act took place. What a pity.
