So her defense is "he didn't do anything but was 29 and going to meet someone he thought was 14"? So maybe he didn't actually touch a child but had the intent to....my question to her would be "What was he going to meet this girl he thought was 14 for?" And "if he would drive that far to meet a 14 year old, what would he do if/when he has easy access to a 14 year old (or other children)?"
I would guess that he is now a registered sex offender. Try to find it on the state's registry. Maybe check w/ local authorities because I would guess they have to notify those in his neighborhood. It is then reasonable to share that info with those you know would otherwise allow him access to their children.
I know here in DE, a registered sex offender is limited in what they can and can not do regarding being near children. For example, they can't work at a school or daycare but if, for example, their work takes them to the school to dump their trash cans (like in a trash truck) they can do that...to the can, dump it, and leave....period. The company knows they are an offender (they are registered and the police notifies the employer). Some companies may not allow it but others may especially if they are not a high risk offender. The wedding photography may not be an issue provided he is not having unsupervised access or alone time w/ the kids but just carrying equipment for his wife.
