Rule #1, never give the police/prosecutor access to anything belonging to you unless you know exactly what's on it. It can always be used against you in court.
“It is a no win situation for him”
That’s true...and I would agree with you, if the case were still in Phase A - Phase A being when the DA decided not to prosecute. Now that we are in Phase B, a media circus driven witch hunt by a special prosecutor, Tracy Martin lokks very, very bad when he witholds information. He started the media circus...and now its too hot in the kitchen?
Heck, if I were Martin, I would genuinely want to know what was on the phone.
