You said this very well.
Tricia set up this site to help locate missing people/children, help solve crimes, and to get as much information out there as they could. We know that LE comes to this site to see the info that sleuthers have posted. This is the greatest bunch of people, who take the time to look at every angle and come up with theories, look at the facts, and spend a lot of time researching info about the case. This is the best crime forum out there. There is nothing better.
And yes, I believe that YM and many other detectives visit daily to glean info or see something they never would have thought of. I agree that YM's superiors are just trying to make sure that nothing happens to jeopardize this case.
Don't forget that the defense will pick at anything. So sad, but that is the way high-profile denfense attorneys try to derail a case.
