Back to the OP, I just read the appellate court decision, and it really sounds like they were stretching to support the trial court. I don't believe that there was probable cause prior to support the warrant before the officers went in.
I once had a judge explain his opinion about the exclusionary rule as being less about protecting those involved in the case at issue than it was about trying to protect the next person who may be subject to a similar situation. If a cop knows he must get his ducks in a row in order to get a warrant, or else he'll lose his evidence and his case, then he may do the job better that next time, which is in the best interests of everyone.
This kind of stretching of the law does nothing more than encourage police, lawyers, and judges to push the edge of the envelope even further. And that is not a good thing.
