A nice letter, but so what? MF Global did some nice PR work, too. Didn't help those who had funds locked up.
Words are wind!
Oh, and I'd also like to add that "the bad actions of a few" is rather an understatement. A lot more than "a few" bad apples are in the financial industry. What firms like RCG need to understand is that it is not nice letters that restore trust, but competent regulatory agencies and prosecutions for theft and fraud.
Without those, investors know that is no real penalty for criminals to continue their schemes, and therefore they will do just that.
