Did God want people to be unarmed too? Nagin had the police unconstitutionally and without due process confiscating firearms at a time when armed thugs were roaming the city robbing, assaulting and raping hapless hurricane victims.
It was about 65 % black majority before Katrina. Mainly because of white flight to the suburbs. I think that was typical of most American cities.
There were lawsuits filed by the NRA and it was ruled that the police had to return the weapons they had illegally confiscated but by then many of them had "disappeared."
