For details of another 3 UK bankers jailed see The Guardian

It does go on to comment:
("Why don't bankers go to jail?")
Kenneth Peasnell, distinguished professor of accounting at Lancaster University management school, suggests that this question "is driven by a sense of unfairness, there being one rule for the rich and powerful and another for the rest of us … The wealthy seem to get a slap on the wrist for not paying their taxes while the single mother gets locked up for cheating on benefits".

Sound familiar?
