My perception is that SWA do have a culture issue. They have had several runway excursions due to poor approach profiles or landing on inappropriate runways (including due to weather issues), have recently crashed one in NY and now this. It suggests a combination of rushing and complacency. Fior what it's worth, they're not the only company I suspect this of, including some closer to home.
Oh, and Willowrun, you can keep your accusations of professional brethren closing ranks for your own profession - there are plenty of pilots making criticisms here, but try and find a lawyer to sue another...
