Prosecute HSBC bankers for facilitating tax cheats - world petition

If we did it we'd be sent to jail. Why should the HSBC bankers be immune from prosecution?

To UK Chancellor George Osborne, US Attorney General nominee Loretta Lynch, finance ministers and prosecutors: 

Evidence published all over the world shows how HSBC helped criminals and the super rich hide their money and evade taxes, leaving the rest of us to pay for public services. We demand that you investigate and prosecute the bankers who facilitated tax dodging and their clients who enriched themselves at our expense, and tighten our tax laws to stop this happening again. sign here  

In the words of Adam Hills, just pay your fuckin tax! Why is that so hard?
