From an American perspective, a genuinely national police force as ubiquitous as the European ones appear to be on the news is 'odd' because the USA doesn't have a national police force that's nearly as visible to the average citizen.
Sure the FBI is a national police force of sorts, but you don't see uniformed FBI agents patrolling the airports under normal circumstances either.
Perhaps the Canadians and Mexicans on the board would correct me if I'm wrong, but the closest we have in North America to national police forces along the lines of the Irish Garda (sp?) or Italian carabinieri would be the RCMP or the Mexican Federales.
I'm 42 years old and the only time I ever met an FBI or other Federal law enforcement agent was in 6th grade, when a couple of FBI agents came in and gave a presentation to the entire school about the FBI.
It stands out in my mind because one agent opened a violin case and pulled out a 1928 Thompson submachine gun and lectured us on both the history of the weapon and gun safety.
Outside of that, the only LE interactions I've had involved city police, county sheriff's deputies, and the Indiana State Police.
Frankly I'd probably either be thrilled to death or piss my pants if a genuine FBI or Secret Service agent came up and said he needed to speak with me.
