Billions In U.S. Aid Wasted In Afghanistan

(CBS) American doctor Dave Warner is on a mission in eastern Afghanistan to show people back home how billions of taxpayer dollars sent here are being wasted. “When I was here in December,” Warner told CBS News chief forign correspondent Lara Logan. “This was full so you can see they've dug another pit over here.” --- Warner is a public health expert from San Diego who's taken it upon himself to do what no one else in Afghanistan seems to be doing — documenting the failures in reconstruction. He says the system can't be fixed unless those responsible first admit that it's broken.
