Does the FBI even investigate this sort of thing internationally? Does anyone?
Countries outside America do have law enforcement agencies for the most part, so yes.
RCMP is the Canadian FBI by the way.
you might be disappointed. Law enforcement cooperates extensively throughout the World.
I don't :)
I know it's hard to believe, but law enforcement of different countries indeed does cooperate really well, often even if these countries don't have very good diplomatic relationships.
And it's not just Interpol/Europol.
So, yes. Apparently.
