Is this another case of Obama administration willful ignorance or just incompetence

Daily Mail:

EXCLUSIVE: Hillary's emails WERE for sale on the open market but the Obama administration didn't go after them, says US intelligence official

A U.S. intelligence agency was aware during the summer that a collection of Hillary Clinton's emails was available for sale, but never gave its agents permission to obtain them, DailyMail.com can reveal. A well-placed official inside the agency told DailyMail.com about the U.S. government's interactions with an eastern European man who put them on the market, and said the U.S. could have obtained them. That discussion was spurred by a dubious claim from the gossip website Radar Online that 32,000 messages from Hillary Clinton's now infamous private email account were for sale with an alleged asking price of $500,000. 'I'm not saying we could have gotten her entire email account. I'm not even saying for sure that what has been on the market is genuine,' the official cautioned.

I don't think this administration really wants to know what happened to those emails.  They are probably still available and perhaps the FBI will try to locate them and retrieve them.  That would be one way of showing they are serious about their investigation and national security.
