Background
With regards to the UK government.
I have recently been involved in a debate stemming from figures mentioned in this blog post (the blogger was advocated by Occupy London's facebook page and verifying the level of "over-sensationalism" portrayed in the post would make or break my relationship with them both).
Here are the bare bones of what the blog post claims:
Bankers cost this country 456.3bn in fraud.
People on the dole cost this country 1.6bn in fraud.
0 bankers are sent to prison for fraud.
6000 people on the dole are sent to prison for fraud (/yr).
Politicians had to bail the bankers out with 1.2tn, leaving the next generation with 3 times more tuition fees to pay.
I did post (twice) on that blog post, asking for citations, but they have not yet replied. So I turn to Stack Economics for the first time for help with either verifying/debunking two claims (100 rep points is not from involvement on stack: economics):
Questions
(i) Where (if anywhere) does the 456.3 billion come from?
(ii) Where (if anywhere) does the 1.2 trillion come from?
