I caught my (now ex) husband (of 18 months) downloading incestuous kiddie porn on his laptop and called the cops. To make a long story short, they found over 1100 images on his computer, including infants and toddlers being raped, as well as video images from hidden cameras in our home (three girls under 15, 2 mine, 1 his).
He got 30 days in jail and 5 years probation.
Michigan.
I've screamed and hollered and written letters and thrown hissy fits, but nothing happens. After a while, people just ignore you.
