Now, I partially agree with this sentiment, and I partially disagree.
I would suggest that
@JRumpel3 attempt to speak to a FBI representative if she has not yet so done. The RCMP and FBI are like any other government organisation in a corrupt government/corporate body. There are a few good people in the lower ranks, but unless you get to talk to the few people who are door kicking warriors, they might just scrawl a bit of stuff down, hang up the phone/delete the email, and throw the notes in the bin. They need to be put in a position where they are forced to attempt to do something.
Generally police forces will not accept complaints from people outside their jurisdiction, even against criminals operating in their jurisdiction with clear evidence, even though Canadians can speak American just fine. They will generally request that you contact a police force in your own country.
This sounds like excessive bureaucracy to go through, but consider this. If Jessica rings up the FBI, preferably records the call (Washington state has two party consent so one might have to give notice to do this, even with law enforcement operatives), and asks that they make contact with the RCMP about his child grooming behaviour, the FBI are in a position where they are accountable to a voter (doesn't mean much, but it's better than nothing) and a person who can agitate in the local news media to threaten their jobs (does actually mean something) who has spoken to them directly. The FBI is thus on the hook to at least attempt to get the RCMP to pursue this pedo.
