No one is saying that if someone has a real tip they should stay quiet. What many of us are saying is that the public are not experts entitled to details of a professional investigation because you think they’re not solving it quickly enough. It just doesn’t work that way. There’s tons of information they have that we don’t and we aren’t entitled to it. And what I believe the poster you’re responding to was saying was that they don’t need the public’s help in a specific direction, with relation to the supposed vehicle tip. Of course they need the public’s help when and IF that public knows something pertinent to the case. Not just general brainstorming. Otherwise, LE absolutely should be assumed to be on top of it or going in the right direction, if a direction is stated, until and unless something comes out that indicates they’re mistaken. You know why? Because they know everything and we know close to nothing. There is a reason for the things they do and we aren’t privy to it. Of course they’re not infallible. There have been mistakes. Usually those closest to the victim are the ones who determine that. But the solution to that is not enlisting curious, amateur detectives from among the public who arrogantly believe they’re entitled to know investigative details and that they will be able to solve a case that LE can’t.
