If American law enforcement authorities have some balls why don't they go after their corrupt bankers? Their bankers have been engaged in criminality upon criminality upon criminality and all they have to is pay some fines which are minuscule in comparison to the amount they robbed, in return for charges being dropped, and admission by the prosecuting authorities of no wrong doing. This is how spineless these European countries are. United Kingdom you know who I'm talking about. And it looks like Switzerland has also joined the list. Some of you European countries are so despicably shameful.
