MALVEAUX: The Pentagon says it deeply regrets the airstrike that killed 24 Pakistani troops in November, calling it a result of inadequate coordination with the Pakistani military. Barbara Starr is live on the details of the investigation. How significant is this, Barbara? What went wrong?</s>BARBARA STARR, CNN PENTAGON CORRESPONDENT: Well, you know, Suzanne, there are both military and political implications to this, of course. The Pakistanis remain furious about all of it. They would like to see an apology from the United States from President Obama. That may not be anything you see any time soon, of course, because the president in the middle of a political season will be very cautious about appearing on camera offering any apologies for the United States. That's something the Republicans have, of course, criticized him for doing in the past. Militarily, what are the implications? This is a situation where a fire fight went terribly wrong because neither side really knew what was going on. U.S. forces landed on the border of Afghanistan/Pakistan on the night of November 25th, came under fire, and called in fire back, not realizing that they were firing on Pakistani military positions. There was bad information, bad coordination, bad maps that led the Pakistanis to say, oh, well, you're firing where we think you're firing, that's about 14 kilometers away, we have no situation there. It turned out, of course, that U.S. troops were firing right on Pakistani military positions and didn't know it. So this remains a very tense situation between both countries. Even though the investigation is done, look for some frosty feelings for some time to come.</s>MALVEAUX: All right. Barbara Starr, thank you. So you see players get hit hard in football, right? Now former NFL players are suing the league. We'll look at their claim about the link between concussions and brain damage.
