My name is ***** ***** I am an experienced criminal lawyer.
Not only are these acts all illegal but they can get him many, many years of prison if he were to be convicted of such offenses. And, of course, he would face lifetime registration as a sex offender.
If he is also making and distributing videos of this sort it's possible even that the Federal government as well as the state of Louisiana would be interested in what he is doing.
I assume, and you can correct me if I'm wrong, that you are asking this question because you are wondering if you can report him. The answer is that anyone can report a crime, and you would not have to be one of his victims in order to be able to report him to the authorities. If you gave the police enough specific information to give the police a reasonable belief that these crimes were being committed, they would have probable cause to be able to get a warrant, show up at his home, impound his computers and find the contraband and arrest hiim.
If that's what you want to do, you could go to the police with the information you have and express your feelings that charges should be pressed, or you could speak directly to a prosecutor in the sex crimes division and report your family member to him or her.
If this is not what you wanted to know please tell me and I can expand my answer.
