Do you believe Leslie Van Houten, former Manson family member convicted in the killings of Rosemary and Leno LaBianca, should be granted parole after 47 years in prison? [Details]?

Really, it goes to the heart of the debate on whether prison can ever serve a rehabilitative purpose.
19 at the time of the murders during the ‘turbulent’ 60’s, Van Houten is now 66.

So. Why was she put in prison?
To punish her?
To protect society from her?
Retribution for the families she destroyed?

If Rosemary and Leno LaBianca had had no immediate family, would Van Houten still be in prison today?
