After I got a job at Canada, I was told by an co-worker that they scold the cops as pigs sometime when I was working with him, just like we call police in the way of "Dogs on the road".
Two days later, when I was passing the Vancouver Police Bureau, suddenly, I saw an old guy was standing in front of the Vancouver Police Bureau, with a huge white board in his hands:"BC's Biggest Pig Farm". Vancouver Police Bureau is located in China Town of Vancouver, the most crowded place in the city. People including cops passed by the old guy like he was not there, nobody was surprised.
Never had I been touched by this scene. Canada has the best legal system in world, how dared the guy insult the police in that way? My co-worker explained it to me with a proud smile: He dared to show his dissatisfaction just because Canada has the best legal system in the world!
