Google could offer not to bring a civil suit against him, but it sounds like criminal charges are on the table and he's trying to avoid anything that might help that investigation.
Here's a recent example: a friend of mine was raped and strangled to death last month. They caught her alleged murderer last week. When the media got a hold of it, they found out that he had been accused of rape and attempted strangulation five years ago, but police decided not to press charges because the victim wanted to let it drop.
So yeah, it happens; it's just a spectacularly bad idea for the police to do it. If they hadn't declined to file charges, my friend and another murder victim would probably still be alive today.
