What is most appropriate, cones of shame or tarring and feathering?

Sir, in “Banks at risk” February 7, notwithstanding that you, at long last, write about the incestuous relations of banks with national government and admit that many countries see banking as an extension of the state, you mention only the taxpayers subsidies to banks, but ignore the immense subsidies governments collect, in terms of more public debt and at lower interest rates that what a free market would allow, as a result of being able to borrow from banks without generating, when compared to other borrowers, as much capital requirement. 

Current bank regulations, produced by our banking central planners, decided that the only thing that matters is that banks do not default, and this set our banks on the course of creating huge excessive exposures to what is officially deemed not risky, and to equally dangerous underexposures to what is deemed as risky. 

That our banks are now at risk? Ha! The whole Western world is at risk 

How are these regulators now best shamed, having them parade down Trafalgar Square wearing cones of shame, or would tarring and feathering be more appropriate.
