I don't understand why you repeatedly insist on restricting your comments to marijuana when you mean all crimes.
One of the contributing factors that encourage prison rape is prison overcrowding. Much of the prison overcrowding problem is due to mandatory minimum sentences imposed for drug-related "crimes", mandated by pro-WOD politicians.
The WOD itself is an abomination, and the incarceration of people for pot is one of its most abominable facets. That's why I emphasize marijuana "offenders" when discussing the really insidious crime of prison rape. If that 19-year old kid in Florida that was victimized by a prison rapist a few months back was your son, you'd no doubt feel the same way.
