I think B's conclusions are essentially the same as mine (because he was the one that worked most of this out in the first place), but he gives a nice breakdown of the puzzle. He doesn't speculate as to why the RCMP did not pursue the "technical data" from Stormfront, merely notes that "a closer look at the evidence wasn't possible given jurisdictional issues".
I, on the other hand, would speculate that Stormfront owner Don Black, who was instrumental in filing the original complaint, could have simply handed over this technical data--presumably logs--to the RCMP (as was done with the original IP address) but, for whatever reason, chose not to, and the jurisdictional issues that arose were the kind that would have been involved in compelling an American website to provide material to Canadian authorities.
Black would not want to hand over his logs to the RCMP, of course, since this would expose many of their Canadian members to prosecution for hate crimes.
And it is far from clear what shape the logs themselves were in. Or, indeed, whether Black ever consulted them. (It is likelier that he merely used his bulletin board software's lookup feature.)
How true how true.
