I found child porn on my grandparents computer but I never told anyone
What was your reason for not telling anyone about it?
I did not want the cops to know and arrest my grandparents.
If your parents have child porn on their computer, you need to consult the cops. I know you're scared, but that's really wrong and illegal.
My parents just want to know that they are doing it again.
It is a better idea to talk to the cops before your grandparents harm anymore children. While it is your family, you should really speak up about something like this.
