The ridiculous violence in N.O.

Can anyone answer this:

Why are there hundreds of murders in New Orleans, yet across the parish line in St. Bernard you rarely hear of a murder. Same goes for the river parishes and down the bayou. Does anyone really think poverty does not exist in our fishing communities along the coast? Are the best schools packed in St. Bernard and Plaquemines parishes? What is it that makes the metro New Orleans area so freakin' dangerous????
