Sorry, Hawkeye, in 1977 what Polanski did to this child was considered shocking and outrageous, just as it is regarded the same way today. No laws have been re-written or changed. When was it ever acceptable for an adult man to ply a 13 year old child with alcohol and drugs and then sexually assault her?
Free love, even in the 60's, referred to relaxed sexual behavior among adults, not to adult/child sexual assaults.
Polanski was judged by the standards of the time. In fact, he was sent for three months worth of psychiatric evaluation to make sure he wasn't an even more dangerous sexual predator. His behavior was seen as abhorrent at the time of the crime, even in Hollywood.
You seem to have some problems with "feminists". Why, because they have helped to enforce existing rape laws? They haven't reconfigured any laws, rape has always been rape, and child sexual assault has always been child sexual assault.
If Polanski had plied an adult woman with drugs and alcohol, and coerced her to submit to sexual activity against her will, he would have been guilty of rape. That he did this to a child was as shocking and unacceptable in 1977 as it is in 2010. He raped a child. No amount of "artistic talent" excuses that behavior. What Polanski did was considered deplorable then and it's still deplorable.
