Where did I say it was legal to hide the ball?<quoted text>
I think you need to re-familiarize yourself with Rules Of Criminal Procedure - Rules Of Discovery.
Take note of "Constructive Possession" by "State Acting Agents.
I think you're implying that it's legal for the State to play hide the ball - so long as there isn't a report or a paper trail.
If so, your thinking is seriously flawed.
If there is no written report, no one is the wiser if that is not used during the trial.
I think you should familiarize yourself with how the game of legal chess is played. All prosecutors don't have clean hands, IS what I'm saying.
