Incredibly, the Internal Revenue Service told Congress that the computer hard drives of seven employees all crashed during a critical episode in the Lois Lerner investigation, with important e-mails lost and forensic techniques for recovering data a failure [“IRS cannot recover all e-mails related to probe,” news, June 17].

For years I supported networks, servers and computers at a major mutual fund company, which obviously had far fewer resources than the IRS. Countless times I retrieved files, including e-mails from off-site backup tapes. Such retrievals, necessary due to file age or server crashes, were easy to accomplish, even decades later. This story of lost IRS e-mails is simply deceit, and participants of this charade should all be indicted or impeached for permitting such a travesty.
