BBM: There is not a doubt in my mind that police know exactly who was where when William disappeared, and where William was last seen (except by a possible abductor). Police sometimes do not give a lot of detail because they do not want to imprint suggestions into our minds. From what I have read, they generally prefer for people to come forward with fresh information that has not been influenced by police suppositions or other witness accounts.
I think the only thing that they would not know for sure is exactly how long it had been since William ran out of sight. 5 minutes could be 3 minutes or 8 minutes or 10 minutes or maybe even 15 minutes. And they probably do not know exactly where William was when he disappeared, of course. Though it is possible that they have little footprints in the dirt that give them an indication - except they could have been smeared or destroyed by all the searchers running around.
I don't quite know where you're going with this. I'm not discussing "who was where when William disappeared", quoted from your previous post above. By all accounts, it
appears the police have no evidence as to where William was last seen,
other than witness accounts, which in my opinion, can be tenuous. As I previously said "
it's important to know exactly where he was last seen and where he disappeared from", bolded by myself quoting from my previous post,
other than witness accounts, as the sniffer dogs did not pick up any scent. As per my previous post, "
Sniffer dogs have failed to pick up any scent of the three-year-old William Tyrell on the NSW mid-north coast" (bolded by me) and "Neither police sniffer dogs nor cadaver dogs had been able to pick up any sign of the boy, Fehon said." (also bolded by me). Now it may be a case that the police meant to say something along the lines of " ... neither police sniffer dogs nor cadaver dogs had been able to pick up any sign of the boy, other than where he was reportedly last seen by witnesses", however, this is not what they said, and I am only concerned with facts as we know them.
It's not a question of police not giving a lot of detail, it's a question of the information they
have given. I personally can see no logical explanation as to why the police would intentionally want to mislead the public, if that is what you are suggesting. In fact, in my opinion, their cause would have been better furthered by
not releasing any information about the sniffer dogs failing to pick up William's scent if as you said in your previous post "they do not want to imprint suggestions into our minds." I don't quite understand your logic in that sentence, or where you are trying to go with it.
Did you read the link about the sniffer dogs? It is improbable the dogs would not have picked up any scent from William whatsoever. In my opinion, it's also improbable that they would not have used the sniffer dogs around the confines of the actual property, as there have been cases where missing children have been found in obscure places (such as the boot of a car, for example), and as William was clearly missing, I would have thought they would have been extremely thorough. Indeed, according to the various news reports, they were extremely thorough. Which then leads back to the question, according to the current evidence, as we know it, why was there no scent of William found at all?
