Globally, it is more than likely that organized crime is buying elections, police, and university administrations via the banks.*
Organized crime now has the capacity to do this because we began to deregulate banking with the Tax Reform Act of 1986 (http://en.wikipedia.org/wiki/Savings_and_loan_crisis#Tax_Reform_Act_of_1986), followed by the Gramm–Leach–Bliley Act of 1999 (http://en.wikipedia.org/wiki/Gramm–Leach–Bliley_Act).
The result was to make banking insanely profitable for globally operating organized crime groups--groups which are in turn, highly liquid, making them very attractive to the banking system.
Here is proof that it is of global concern:
The US Declares War On The Yakuza (July 27, 2011)
And, more proof:
How a big US bank laundered billions from Mexico's murderous drug gangs (Saturday 2 April 2011)
Consider also: the independent professional military organizations, such as Blackwater (http://en.wikipedia.org/wiki/Xe_Services), with deep connections to national militaries around the world, that are now for hire.
If we do NOT re-regulate the banks, we will never get out of this mess.
We are in more danger than we realize of losing our democracies, and control of civil society.
