Dad of 6-year-old Sandy Hook victim fighting misinformation

Only on "CBS This Morning," the father of a Sandy Hook shooting victim is telling us about his fight against misinformation. This comes after a major legal ruling against a man who called the mass shooting a hoax. Lenny Pozner’s 6-year-old son, Noah, was killed in that 2012 shooting. Pozner tells "CBS This Morning" co-host Tony Dokoupil why he has made it his life's mission to change tech company polices.
