Is what the Fed doing illegal?

Something is very fishy about how the Fed goes about buying the Debt from the U.S. Treasury. They are managing to control the media and people's perceptions to what they are doing, but it just feels wrong. They are manipulating the Debt markets in America. So, anyone else that manipulates as long as prices are going up is considered OK, but not when prices are going down. This huge discrepancy creates false valuation in markets that result in very strong resets, when the fallacy is revealed.

I predict that this will happen as well at some point in US Treasuries. The worst part is that the Fed will be faced with crushing mark-to-market losses, but will never mention anything...
