Argentine journalist Rodolfo Walsh’s Operación masacre is an investigation into the extra-judicial assassination, on the part of the Buenos Aires provincial police, of a group of men initially suspected to be part of a Peronist uprising on the night of June 9-10, 1956. As much as an account of what actually happened in the hours shortly before and after midnight on those dates, the book is also the story of the investigation itself. Walsh describes how he was initially reluctant to follow up on a rumor about the events he had picked up in a café, but then threw himself into the pursuit of the facts, driven by outrage at the authorities but above all by sympathy for those who had, against the odds, actually survived. He soon finds himself on what is effectively a crusade for recognition and justice, though he is aware of the price he may one day pay for the trouble he is perceived as causing. Indeed, much later, during the military dictatorship of the 1970s, Walsh’s voice is finally silenced when he is killed by soldiers in a confrontation in downtown Buenos Aires, his body dragged away to be burned and thrown in a river.

But Walsh evidently believes that the dangers inherent in seeking out the truth are more than merely personal. In the introduction to the first (1957) edition of the book, he writes that “too much truth can lead to madness, wiping out a people’s moral conscience.” But he goes on implicitly to welcome this eventuality: “One day the tragic history of the June killings will be written down in its entirety. And then we will see the shock overflow our borders” (265). The truth, in short, is something not to be taken lightly; its effects are collective and potentially catastrophic. But ultimately we should take the risk of the madness and destruction it brings with it. After all, he concludes: “I happen to believe, with complete earnestness and conviction, in the right of every citizen to share any truth that he comes to know, however dangerous that truth may be. And I believe in this book, in the impact it can have” (266).

But Walsh is not content simply to leave things there, as an ominous warning for the future. He himself does whatever he can to ensure that the murky details of this “tragic history,” still incomplete when he first publishes it in 1957, should in the end come out. A second and a third edition of the book come out in 1964 and 1969 respectively. Each time he feels that he has better pinpointed the chain of events and responsibility that led to these mostly innocent men having their lives ended or, if nothing else, transformed as they were grabbed from an informal gathering in a private house and finally gunned down in a (frankly, botched) execution on the outskirts of the city. But with each new edition of the book, one also feels increasing frustration and even despair on Walsh’s part as the officials he identifies as the guilty parties continue to evade any repercussions or consequences. In the end, as in the epilogue to the 1969 edition, Walsh’s tone becomes almost frantic and apocalyptic as he expands his frame of reference to “a portrait of the dominant oligarchy” and concludes that “within the system, there can be no justice” (299, 300).

In the first place, the problem is that the investigation threatens to become interminable. The truth “in its entirety” is not so easy to uncover. There are numerous points at which Walsh admits to doubt or uncertainty, in part because witnesses are absent or unreliable, or because their testimonies contradict each other. In the end, even relatively basic facts such as the number of men taken out to the killing zone elude him. The book’s opening paragraph has to admit that “We will never know it all” (31). There will always be a penumbra of doubt however dedicated the effort to ferret out the facts. And so, for all Walsh tries to give substance and materiality to events and participants, they remain strangely ghostly, just out of reach.

But there is a worse possibility: that Walsh may manage to uncover the truth, or enough of it that should count, and yet nothing might happen anyway. At one point in his enquiry, seeking to track down yet another survivor, he comes across a little girl in the street who tells him “The man you’re looking for [. . .] is in his house. They’ll tell you he isn’t, but he is.” To which Walsh replies: “And do you know why we’ve come?” Coolly, calmly, the girl responds: “Yes, I know everything.” And though we never find out this young girl’s name, Walsh gives her one: “OK, Cassandra” (24). For Cassandra was of course the Greek princess, daughter of Priam, who was blessed with the gift of prophetic knowledge but cursed (by Apollo) never to be believed. In fact, Walsh does believe this girl (and finds the man he is looking for as a result), but he must already be thinking of himself as a Cassandra figure, destined to reveal the truth but to no avail. No wonder at times (and increasingly as new editions come out), his prose becomes increasingly strained and reliant on rhetoric as though he were trying to compensate for the fact that the truth alone will never set us free.

For the real scandal is not so much the truth itself as the fact that truth-telling does not have quite the power that Walsh ascribes to it. Perhaps it isn’t all that dangerous. Perhaps “speaking truth to power” (as they say) only puts the truth-teller at risk. Or it may even be that when Walsh is finally gunned down, it is for something else entirely.
