Obviously you can’t do anything but delete it and secure the computer.
Look at the people here. You want to report a crime but half the crowd is ready to accuse your BIL as their prime suspect. Chances are the police will be even less forgiving then the potential jury.
Its a shame.
You are right. If it were my computer I would be tempted to destroy the hard drive, bury it, get a new comp and make sure I had a secure connection with it.
Cheaper than hiring a lawyer to defend yourself against something you didn't do.
Its a shame.
Not really. I have been involved in numerous cases that involved child porn. Most of these crimes start with an outcry witness. Many of them are family members that find the material on the computer. It happens, and the investigators know this. What looks bad is if they try to cover it up.
