Oops! Sorry, man. Here's a new computer for you. (Did they lose the other one?)
As is usually the case in situations like this, the TSA hasn't admitted to doing anything wrong, and in a letter to Elliott's attorney, simply states that his subpoena is "being withdraw [sic] as no longer necessary."
(Nod to Anonyman, who also notes that it seems odd that confiscation was even an issue in a civil case, before there was a hearing.)
(UPDATE: Shawn notes, in comments, that this lady had her laptop "blown up" by Israeli TSA. And, it appears to be true. Yike!)
