No one is claiming the Google search wasn't important. It clearly was. However, it wasn't the 'only' digital evidence the jury had to work with from the Cyber Task Force guys.
The next jury will still have the Google search to consider again and they'll hear more from the defense witnesses on "spoilation" of computer files. In addition, the next jury will have digital evidence the first jury didn't have -- and that is evidence showing BC's laptop had a system event log that will prove he was configuring (or attempting to configure) a 3825 router the night of 7/11/08. At that point the Google search will not be the only important/compelling digital evidence pointing to the defendant's involvement.
And that will be fantastic. And if that evidence is correct and can't be refuted, will also probably lead to a conviction again. And hopefully there will be a different prosecution team and judge as well considering the crap that went on in the first trial. And hopefully it will be a fair trial, because the first was certainly not.
