The Mayor made no effort to protect the lives of citizens by safely evacuating the jails in advance of the storm. Prisoners from New Orleans Parish Prison sit on a freeway overpass, September 1, after their jail was evacuated by authorities.
The Mayor in New Orleans doesn't have authority over the prisons. It's the Orleans Parish Criminal Sheriff (who is elected) and then the Attorney General of Louisiana. Where is the Sheriff? - - - who knows, I haven't seen him once - maybe he left with his family!
