Here's a link to an article from today's paper:
http://bizbeatblog.dallasnews.com/2014/10/dallas-based-trinity-industries-hit-with-175m-verdict-total-damages-could-near-1-billion-in-guardrail-case-brought-by-whistle-blower-josh-harman.html/
The article is about some lawsuit about a company that made minor changes to their product, but the minor changes caused the product to be "less safe" and the company committed fraud by not telling anyone about the changes. Blah, blah, blah.
What was funny [sarcasm], though, is a paragraph near the end of the article:
"Karen Dyer of Boies Schiller and Flexner, one of five attorneys who argued the case for Harman, said in her view the evidence that had the strongest impact on the jury was an 2004 email that showed Trinity executives had concluded the change would save the company money, and suggested that they had purposely not told the FHWA about the change."
So basically, they could find a 10-year-old email, but all of Lois Lerner's recent IRS emails have magically disappeared, never to be recovered.
