Not sure I understand, but I think you're asking about my question mark. Upthread, posters were implying that the location that was searched with the sniffer was close to the original SWAT operation. If they didn't find anything, though, does it still indicate anything about that original SWAT location?
To answer my own question, perhaps it does, even if they didn't find anything, in that they would have had some evidence leading them to the location they "sniffed". I don't know. They've needed some sort of evidence for two search warrants, and none of that seemed to pan out, or at least so far. Hmmm.
