Webb's reporting in "Dark Alliance" remains controversial. Many writers discussing the series point to errors in it. The claim that the drug ring of Meneses-Blandón-Ross sparked the "crack explosion" has been perhaps the most criticized part of the series. Nick Schou, a journalist who wrote a 2006 biography of Webb, has claimed that this was the most important error in the series. Writing on the "Los Angeles Times" opinion page, Schou said, "Webb asserted, improbably, that the Blandón-Meneses-Ross drug ring opened 'the first pipeline between Colombia's cocaine cartels and the black neighborhoods of Los Angeles,' helping to 'spark a crack explosion in urban America.' The story offered no evidence to support such sweeping conclusions, a fatal error that would ultimately destroy Webb, if not his editors."
