IF HE WERE INNOCENT
he might tell the police immediately because it could affect the investigation, but not tell the family because it only adds to their pain and confusion.
When, exactly, would have been the right moment to tell them? Before or after the cry-fest? Just before a press conference?
"Oh, by the way, I was cheating on Laci at the time. Just thought you should know."
So I can't blame him for not telling her family or the press, although I can blame him for cheating in the first place.
So long as he did tell the cops immediately he did the right thing then.
What was her alibi?
