the knife
The reports are that a knife was found on OJ's estate back in 1998. You can read about it on TMZ. I have two points.
1.) How did the construction worker for turned it over to the off duty cop not find it weird that in the 18 years since then there was no mention of the knife in the news at all?
2.) The retired cop who had the knife all this time should be brought up on charges. Obstruction of justice, withholding evidence, whatever the legal reason would be.
