I think the federal RCMP are seriously trying to nail down Tampon John. If I were to phrase things optimistically, I might say that the feds and local cops are co-operating. Non-local police are brought in at great expense to conduct the search and investigation due to John's tendency to make everything a legal matter. The police want things done cleanly by a neutral party that can't be accused of transphobia or embroiled in accusations of bias. I am not a lawyer, but it seems to me that he would have a tougher time making a human rights complaint against the RCMP versus a local detachment with which he has a long and weird history.
Less optimistically, one might say that the Langley detachment has let things get out of hand to the point where the Big Boys had to step in to fix things.
Either way, hopefully they'll find whatever revolting CP is surely stashed on John's computers or browsing history.
