This is a great run down of how banks can get away with manipulation of trillions of dollars. It shows that governments cannot be trusted, governments will protect banks for frauds committed against citizens.
Governments will bail out banks when they screwed up, and also protect high up bank executives from going to jail. This is the two tier justice system we live in, both in Canada and else where in the world, the corrupt rich and wealthy bankers and politicians get special treatment.
