Porn and demons

This one is hard to write, and will be hard for some to read, so I apologize in advance. There is no way to sugar coat it, to make it easier to swallow.  What happened to the 2 boys in my opinion is torture, but apparently legal in my state.
KR placed our 2 boys in a room. For "hours" (in their minds) he interrogated them (they were about 7 and 9) until they admitted they had watched pornography.  Of course they hadn't, but they thought if they admitted it, he would stop. The boys didn't even know what pornography was, but they just wanted the questions to stop. But they didnt. KR then demanded to know where they had watched it. The boys said " I don't know" over and over. Finally, he forced them to say my husband and I had made them watch it. KR then took the boys to the computer and pulled up multiple videos of people who were supposedly possessed by demons, and showed them to the boys. He told the boys they would be possessed by demons for watching pornography.  That night the boys thought there were demons in their room. When they came home a few days later, they told my husband and I what KR had done. They were terrified, and feeling guilty that they had lied about their stepdad and myself. I hugged them and told them it was not their fault,  and then we prayed and talked about the fact that there were no demons in their room, and no,  whthey would not be possessed. My mom and dad came over and prayed with them too, as my boys trust grandma and grandpa on spiritual issues alot. The counselor was able to get them in the next morning on an emergency basis as well, and I think that helped them through the fear too. Our state does not consider emotional or mental abuse "abuse", so nothing could be done.  Helplessness is the worst feeling when your children are being hurt.
