How many bankers are in jail so far?

None - go talk to Eric Holder who is too busy running guns to drug cartels and laundering drug cash.
Or go talk to Getihner and Summers
Don't you get it yet? Eric Holder and Obama are there to protect the banksters, not prosecute them. Obama even said so directly to them as reported in the book Confidence Men. Even the bankers themselves said they were shocked at how easily Obama went on them for their crimes.
