[Avodah] Madoff's Sons

[Harvey Benton]

If someone has a chazaka of being a child molester, ganef or a murderer C"V, why would we wait for a victim "lefanenu"??  What about our obligations (Al Taamod Al Dam Reecha) to potential victims? Should Maddoff's sons have waited till Madoff met/phoned his next victim (=lefaneinu?) and then turned him in?    Or should someone wait for a child molester to be in seclusion with his next victim -- and only then turn him in (if it is his parent)?    What exactly defines "lefaneinu" and when would it apply?  Also if his sons didn't turn him in for any substantial length of time, and people found out about it, it could cause a CH.
