Are feds making big-time move on mortgage fraud?

A major federal lawsuit against Deutsche Bank's mortgage arm certainly raises that issue.

Here's the nut graf that says this likely isn't isolated:

"It would not be a fantastical stretch to think we are looking at other lending institutions as well," (Pheet Bharana), the U.S. attorney in Manhattan, said.

The details? The lawsuit is for more than $1 billion and alleges:

MortgageIT recklessly approved 39,000 mortgages for government insurance from 1999 to 2009 "in blatant disregard" of whether borrowers could make the required monthly payments.

At the same time, I don't know what percentage of the company's loans this involves, how much pretrial negotiation was attempted or other things. This may not be too much beyond the slap on the wrist level.
