    "abstract": "Wang, Kuzmich and Dogariu, in their 20 July, 2000, Nature article, describe\nan experiment ostensibly measuring superluminal speeds of 310c via a few\npercent shift in time of an optical pulse undergoing anomalous dispersion in a\npumped medium. This paper seems to have become part of the superluminal lore\nand is often referenced as a profound example of superluminality. We have\nclosely examined the article and find serious flaws that need to be addressed.",
