According to Colorado Law, such a charge can't be pleaded down. Kobe is either a registered sex offender, or completely exonerated. There is no middle ground.
Think about the transcript yesterday. The judge said no plea if I set a trial date. Would the judge have said that if it was true you can not plea down the charge.
Face it, you can pass all the laws you want against plea bargans, but if the DA drops the charges the court can do nothing. If the DA refiles 3rd degree assault charges, the court can do nothing. Laws trying to stop plea barganing are basically a waste of time.
