Latest on BATF's "Fast and Furious"

FWIW: Latest government report on BATF's Operation Fast and Furious.  Haven't had a chance to look at it in detail, but it appears to conclude that AG Holder had no prior knowledge.  Hate to sound so cynical, but I am always wary of a government agency that investigates itself and about redacted reports.  I realize there are legitimate reasons for redactions (e.g. protecting informants), but in a highly politicized administration facing a tough re-election campaign, I find it hard to be trusting. Further, as noted on p. 4 of the report, a number of  key witnessess could not be located, refused to cooperate, etc. Perhaps this is an OIG with integrity, I don't know.  Thanks to Henry Schaeffer for the link.  If anyone has time to go through it, please share your impressions, conclusions.
