Why should George Soros be licensed to kill and not the bankers?

Sir George Soros in “America must face up to the dangers of derivatives” April 23 describes these as “a licence to kill” and he is wrong.

Just as a gun a derivative can do good or bad depending on who pulls the trigger on what and with what accuracy. In this respect, and given that in matters of investment George Soros could also readily qualify as just another gunslinger perhaps he should hand in his licence to kill too.
