Put a hidden camera in your stepdaughter's room to capture pictures of her undressing? Spend the rest of your life in federal prison, even for a first offense. (The defendant here is 61, and was sentenced to 21 years in prison. He's very unlikely to be alive when released.)
One more thing. You also forfeit your house. Since it's the location, and hence an instrumentality, of the crime.
So even if you're utterly amoral: Not a good decision.
