Forgiveness and compion for both Victim and sinner?

I just received a letter from our pastor that the school teacher that just recently served 2 years and was convicted of intent for child molestation is returning to our church and community. His family has forgiven him and the preachers have said that he has asked for forgiveness from our loving Lord. The letter was very moving and we as church members are to welcome him with open arms. Of course he will have all of the restrictions that a child molester must endure including never teaching again. What would your reaction be to the slippery slope he started down and the amount of trust the church should allow?
