Katrina: Leaders debated compulsory evacuation
As Hurricane Katrina bore down on the Gulf Coast in late August 2005, the city council had a big decision to make - should they evacuate or not, and if so, should they force people to leave.
For the first time, Sherry Schultz - the city's chief lawyer at the time - has spoken about the dilemma facing elected officials and the criticisms that they acted too slowly.
She reveals that the city's leaders had no idea whether they had the legal authority to make people leave, and no real plan to enforce a compulsory order.
She spoke to the BBC's Gary O'Donoghue on the banks of the Mississippi River.
