It's been five years since Hurricane Katrina devastated the Gulf Coast, killing 1,800 people and causing $41.1 billion in insured damage -- a single-loss record for the insurance industry. Katrina's impact still ripples through the region today, and through Bloomington-based State Farm Insurance Cos., the largest home insurer in the U.S. The company fought through a second storm in the years since, attacks on its carefully crafted good-neighbor image -- led in part by a now-discredited trial lawyer -- over accusations it was trying to avoid paying out claims.
