In a public statement, the DEA claimed to have "infiltrated" the marketplace and to have successfully purchased a large quantity of LSD.[11][12] The indictment contained evidence in the form of hundreds of incriminating emails from 2006-2010, one of which included a comment that described Hushmail, the service they had been using to send the emails in the indictment, as "an encrypted and safe method of communication [which] would not produce e-mails to law enforcement officers."[9] Though Hushmail's complicity with police was not made explicit in the indictment, Wired, Forbes, and the Tor blog connected suggested it would be likely given previous privacy concerns about the site.[2][8][13][14][15][16] The undercover officer who had purchased LSD was party to a several of the included emails. The indictment also indicated cooperation by the U.S. Postal Service and included as evidence that particular defendants had received envelopes at a post office box.[9]
