Shoganai is an important word in Japanese. It can be translated "it can't be helped." It's often used to describe Japanese culture, thinking and values. Shoganai is essentially a philosophy. It says that if something is out of your control it's better to quickly accept it and move on.

This is Caldwell and the Yakuza Rail Mafia exactly. They have lied and conned the public and have made them selves the insiders controlling the bank. A classic Yakuza tactic- rob the bank from the inside, steal and spend public money "legally." Just claim that it "cannot be helped." "Accept your fate that we are liars and thieves because that's how it is done."

Caldwell said there would be a Public Hearing on the rail alternatives - but it never happen! He was just lying to the public to get himself reelected. "We've got the money" Now we KNOW what that means. And its going into the Rail Mafia pockets. "Legal" Bank Robbery. Don't need no stinkin' audit!
