posting about David Kaye the issue has been raised as to why he should be viewed as dangerous (i.e. rodef) when he has not done anything wrong halachically? He is obviously disgusting and not welcome - but should he also be considered dangerous since he never did anything to harm another person and he has a life time of helping others. His major downfall was a sting operation by a TV. station involving what he thought was a 13 year old boy. The whole crime for which he was sent to prison is simply a mental fantasy - and some claim that only according to secular law is it wrong. In order to understand this better let me present the follow case.
You and your wife are leaving in an hour to celebrate your parent's golden anniversary in Florida - so you will be gone for one night.Your younger kids have been distributed to neighbors. However your 13 year old daughter says she is old enough to stay home for one night and says one of her friends is coming over to keep her company.
You do a last minute check on Google maps for traffic conditions and then a quick glance at email to see if there are any important last minute messages. With great irritation you notice that the email is still logged in to your daughter's account - but you also notice an email with a very inappropriate subject line. Pushing aside the concerns for Cherem of Rabbeinu Gershom of reading other's mails - you start reading the letter.
Shock and revulsion hit you as you realize that it is a letter from a 35 year old male who claims to be a rabbi. He has been having an exchange of very explicit sexual communications with your daughter. You notice the exchange has been very intensive and some of the emails have attached nude photographs of him and others which have pictures of her. The last email says he is coming over to spend the night with your daughter.
With your head spinning you think of what you should do in the 30 minutes before you have to leave.
1) Call the rabbi of the shul where you go for daf yomi and who is a world-wide expert on kashrus. 2) confront your daughter and force her to come with you. 3) contact your next door neighbor who has mafia connections who will make sure the guy receives the proper message in a forceful unambiguous manner4) Do nothing since after all your daughter is halachically an adult and it is a consensual relationship. You give yourself a mental note to have a talk with your daughter - when you get back - about how inappropriate it is and that she is only a child and not old enough for these types of relationships. 5) Call the police
