so much crap in that i hadn't got through it all myself yet sorry its seems its neither fish or fowl and the truth is somewhere in the middle.

In a nutshell, they blame the crisis on three things:
*A massively overleveraged financial sector (with FHLMC as the worst culprit);
*Horrible underwriting at every level from loan origination to S & P;
*'Toxic' loan products which - combined with poor underwriting - allowed unqualified borrowers to take out loans they never could have been expected to repay.
Those loans were immediately securitized into the highly overleveraged financial institutions - instead of being held by the originating institutions which would have had skin in the game as to real loan quality - and when they unsurprisingly blew up, the negative leverage effects killed the institutions. This was, of course, made worse by the array of poorly designed (but fee rich!) risk-managing tools that made up much of the secondary markets
