Layout, those are international waters, no one owns them hence if they are asking for papers to prove who is who, it is alright with me. They, the US and Canadian coast guard and DHS are there to do a job and that job is to protect our respective countries. IF some 'sportsman' is inconvenience by the check, go hunt some where else.
AS for Italy and Poland not having issues with invaders there, they have very serious problems. One of the issues with Greece and Italy alike is the amount of money they spend on social programs during the time leading up to deportation. Italy now has a Libyan issue with the amount of refugees who just showed up. Germany has been known to be very very cruel to their invaders, I understand they deport them in record time and make our process look like it Disney created it.
