I agree with this:
This tells me that the house is of no importance to the case. .
I don't agree with this:
I'm thinking that Hoover and DC just went over there to poke around just because..
The PIs went there, according to Hoover's testimony, because the same tipster told DC both places to look. They went to both places at least twice based on this same information.
This alleged tipster must have had some serious validity to DC, because he has said these were the only two locations that he (or anyone in the family, to his knowledge) looked for a deceased Caylee. Hoover also said he understood that all along DC believed Caylee was alive. No random tip was going to go make him look in these two spots. Psychics, crimeline callers, even TES had "tips" that there might be remains in various locations, but DC never, apparently, followed up on any of
those tips. Nor did the existence of those tips apparently ever sway him from the belief that they were searching for a live Caylee. Until this one tipster.
I don't think the house is important to the case - you are correct that LE, FBI, and probably the entire cast of CSI Miami would have been swarming the place if it was. I do not think that LE would ignore it if it had any shred of possible validity. There are only two things important about it as far as I am concerned:
- Why did DC go there
- Why was LE almost immediately sure it meant nothing
LE, in my opinion, could not have disregarded this scene unless they were rock solid on why DC searched there. In order to be rock solid, they would have needed to find out his tipster and question them. If the tipster was sufficiently believable, only then could they decide this location was not involved in this crime. They would have no reason to just take DC at his word, I don't think. If DC could not or would not provide evidence of who sent him there, I think LE would have had to investigate it, just to be sure.
Some people have suggested that LE didn't go there because their case is strong enough without that house, but I disagree. They still don't (to our knowledge) have a firm date/time/location/manner of death. If they had any suspicion that DC was led there to hide, remove, or otherwise destroy some evidence at the Brackenwood house, they would have had to go there and secure the scene and examine what was left. They didn't, so I think that they know for a fact why he was there and that it was simply an incorrect location option, not something meaningful to this crime.
