Exactly, PB. You have to understand the Sicilian culture and their mistrust of the government. To Vito, having grown up where outlaws WERE the law, then the government was not something that you trusted with your life. He also had some first-hand experience with American judges, policemen and politicians that could be bought. He couldn't possibly begin to understand the mindset of someone that was willing to put their life on the line for their country.
