If, when my now adult children were still young, I had ever accidentally downloaded such disgusting stuff, I would have immediately called the police, and probably vomited as well.
When the police arrived I would have expected them to take away whatever Internet accessible items I had, and then taken me to a police station for questioning. I would have also readily agred to my children being taken to their Grandparents, or to whomever completely trustworthy friends or family I had, that both I and the SS agreed were appropriate. If there was absolutely no-one suitable that I knew personally, I would have broken heartedly had to agree to the children being taken temporarily in to care.
If my husband had been the one charged all those years ago with such a horrendous crime, I know that he would have immediately offered to, or agreed to, stay away from the children for the length of any legal proceedings. That would have broken his, my, and the children's hearts, but he would have done it to save there being any chance of the children being removed by SS. If I did not believe that he would have agreed to such an order, I could not have loved him, or have ever been able to be intimate with me, in fact, I would have probably wanted to kill him.
Neither my husband's, or my reactions, to being accused of such an inhumane crime, would have made us not believe whole heartedly in each others innocence, we would have just been wanting to protect our child, or children, from such a dramatic, and traumatic event.
Why @Helpwithsocialservices, do you and your partner, not feel exactly the same?
