Throughout the 1990's, Buckhead had a TREMENDOUS club/nightlife scene.
In 2000, Ray Lewis was in town for an away game or whatever reason. He and his entourage got into a nightclub altercation that lead to a stabbing death... you know, just read his Wikipedia entry if you're not already aware of those details.
Anyway, it was an EXTREMELY high-profile story in the local press, and shortly thereafter the bar and nightclub scene was drastically curtailed.
Now, it's definitely arguable whether this should be attributed to Ray Lewis. The truth is more complex... political pressure from wealthy local residents had been building for years, and the Lewis incident was really just a "symbolic" tipping point. Regardless, a lot us lifelong Atlanta residents tend to remember that incident as one of those miniature 9/11-ish moments where a culture shifts abruptly.
