I meant, does anyone investigate them end-to-end, and not just in their own country? I find it hard to believe that the FBI interacts well with law enforcement in, say, Poland.
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.
