Yeah... right. That's exactly how it works when law enforcement is investigating a serious crime that you allege happened. You just make all kinds of public allegations against others. Then, when law enforcement comes to investigate, you dictate what evidence you will and won't turn over, when you'll do it, how you'll do it and in what form etc.
"After REFUSING to cooperate, I EVENTUALLY made a copy of the knife used in that murder and gave it to police"...
Sure.... sounds legit.
