I believe a 12 to 17 year sentence would send a rather clear negative warning to other law enforcement officers. Beyond the sentence, this guy’s life is forever altered. I doubt that’s lost on many officers.
I just checked the Florida statutes. Exactly this situation is covered, and it is a first degree felony with a maximum of 30 years. So he just got the maximum.
Using or threatening with a deadly weapon, or using injurious physical force, is a life sentence in a rape.
Being over 18 and damaging the reproductive organs of a girl uner 12 during a rape is a capital offense.
