Immunity for what?

I was talking to a friend of mine, non Nuwaubian, and who have very little knowledge of what went on regarding the case of Dr. Malachi Z. York.  A very interesting point and questions arose from this conversation.  The women who testified against Dr. York, these grown ass women who testified against Dr. York received immunity for their so crimes they committed.  Apparently these women testified in court that they brought and offered children to him for the purpose of sex.  And that they also engaged in unlawful sexual acts against minors or children.  Is that what they received immunity for?.  And because of their testimony their illegal acts and crimes became immune to any legal consequences or legal punishments.  But if these women have been involved in child molestation acts for over 5, 10, 15 years or maybe more, ARE CHILDREN SAFE IN THEIR PRESENCE?  Did they received any type of psychological help?  Were they legally forced to undergo psychological treatment by the court system who gave them immunity?  If they live in your community, would you feel threatened?  Because the system have created a tracking device or programs for sex offenders.  Are they considered sex offenders?  Should they be treated as sex offenders even though they received immunity?

You must asked yourself, Why are sex offenders even tracked anyway?  Because they have the tendency to re-act their crimes.  And if these women have been involved in child molestation acts for many years, do they also posses the tendency to commit child molestation acts?
