... Let's see... Trashing furniture and equipment, barricading himself in a room and threatening the RCMP.. Hmmmm... Now that I think about it, that's how you get invited to high-tea and biscuits at Buckingham Palace, right? Maybe buddy was a little peckish after his long flight.
Then again, according to your suggested protocol of customs/immigration practices in Poland, the RCMP should have just 'crippled him for life'... Would that make you feel better?
