So, Barclay made arranges that saved it and negated the need for a state bailout and now some of its senior staff are charged with fraud.  No good deed never goes unpunished.
BTW, the 2008 melt-down is ample proof of what a mess government policy can be.  Forcing Fannie Mae and Freddie Mac into making and insuring sub-prime mortgages, and making such actions a performance measure was a sure recipe for financial disaster.  Remember, sub-prime mortgages were sub-prime to start with and for a reason.  Using these as a "costless" way to give the poor the benefits of home ownership was foolhardy.  It cost the US government and the world economy a bundle.
