Hum Nat (2011) 22:225–246 235 (Tierney 1994:19, 124, 127), perhaps because he saw FUNAI as hopelessly corrupt (Tierney 1994:182–183, 205, 210). He carried mercury into the rainforest, as part of his gold miner disguise (Tierney 1994:71). As part of the act, he did a little pit mining himself, knowing full well that it wrecks the environment (Tierney 1994:139, 155). He illegally purchased a shotgun and carried it into indigenous territory (Tierney 1994:71). Time and time again, he met up with murderers—including self- confessed murderers—and apparently never turned them in to the police (Tierney 1994:69, 115, 138, 149, 163, 396). He flew into remote Yanomamö areas without quarantine (Tierney 1994:172, 181). He stirred up enough trouble that, it seems, he accidentally got a guy killed, because the other man was mistaken for the troublemaking Tierney (Tierney 1994:327). Mind you, this is all reported by Tierney’s own hand, and this is all information the AAA could have found as easily as I had, had they decided to first ask who Tierney was, rather than immediately using him as a reason to go after Chagnon and Neel. Perhaps the most interesting information revealed in Last Tribes is that, in his investigative wanderings, Tierney was fed, housed, protected, and encouraged by the local Roman Catholic priests (Tierney 1994:30, 120, 272, 297, 298). He left his money and real identity papers with the priests (Tierney 1994:50). When he was arrested, it was Bishop Aldo Mongiano who sprang him out of jail (Tierney 1994:216; also indicated in Saffirio 2009). Tierney specifically checked in with and acted as an emissary for this bishop (Tierney 1994:229, 231). At one point in Last Tribes, Tierney remembers having been told, “The bishop is very happy with you” (Tierney 1994:234). I was not too surprised when Saffirio described Tierney to me as “a good Catholic” and added “bishop [Mangiano] was pleased to help him” (Saffirio 2009). As the AAA would have learned, had they bothered to borrow through interlibrary loan a copy of Last Tribes as I did, so much that Tierney revealed in the unpublished Last Tribes was made invisible to readers of the book that was ultimately published, namely Darkness in El Dorado. For example, Tierney’s close relations with the Consolata priests are largely obscured in Darkness. It isn’t clear from either book to what extent Tierney worked with or for the Salesian missionaries, the religious group engaged in a long-running battle with Chagnon, the way Tierney apparently did with the Consolata. But Chagnon himself has noted that the Salesians apparently “opened their records to Tierney and gave him free access to them” (in Hagen et al. 2001:110). After trying, mostly fruitlessly, to sort out the mysterious identity of Patrick Tierney, the man the AAA took as their guide, I was simply left struck with the lovely irony that the founder of the Salesians, Dom Bosco, is today the patron saint of illusionists. Fascinatingly, in our interview, Frechione told me that, since Darkness, Tierney has apparently teamed up with the equally discredited Andrew Wakefield. Readers may recall that in 1998, Wakefield published in the Lancet a highly publicized paper throwing doubt on the safety of the vaccine commonly used to prevent measles, mumps, and rubella (MMR). But Wakefield had failed to disclose what the Lancet editor later termed “fatal” conflicts of interest, and ten of his twelve co-authors retracted the paper. A subsequent ethics investigation by the UK General Medical Council found Wakefield guilty of professional misconduct on numerous counts,
