What do you mean by "supports"? It states that JW's latest FOIAs turned up IRS memos showing some IRS Techs contradicting the sworn testimony of other IRS functionaries. That seems to me to "support" the headline, regardless of whether it provides details. For more detail, you'll have to visit JW's site.
Here are details on the contradictory stories from the IRS --- .... Recent documents from [JW's FOIA] lawsuit against the IRS, which Sullivan is presiding over, showed that IRS technology officials contradicted sworn testimony about damage to Lerner’s hard drive. ... The IRS technology official who served as the source of the “scratched” and “shredded” revelation is believed to have looked at the hard drive after Signor. Sullivan’s order seems to have been motivated by the obvious contradiction.
Nothing in the article states that the techs stated the drive was not damaged. Other sources have said there were scratches... But not this article. The headline is misleading.
