3/31: Families say GM valued money over life; Fateful decision likely saved Wash. dad from mudslide

A day before a congressional hearing on faulty ignition switches linked to 13 deaths, families of people killed in recalled General Motors vehicles told CBS News they want answers on why it took the company so long to issue recalls. A background report shows GM decided fixing the defect would take too long and cost too much; and, a change in weather has made conditions slightly better for search crews digging through mud and debris after the massive landslide in Oso, Wash. John Blackstone meets a father who would have been in the mudslide zone if not for a last-minute change of plans.
