>The timeline is that she was investigeated for Benghazi, and while being investigated, noticed improper emails. She wipes the improper emails, then later there's an investigation into the improper emails. The "evidence" was already destroyed, back before it was evidence.
The evidence was wiped after the state department asked for her emails:
âoeWe learned today, from her attorney, Secretary Clinton unilaterally decided to wipe her server clean and permanently delete all emails from her personal server,â he continued. âoeWhile it is not clear precisely when Secretary Clinton decided to permanently delete all emails from her server, it appears she made the decision after October 28, 2014, when the Department of State for the first time asked the Secretary to return her public record to the Department.â (http://www.nationalreview.com/corner/416125/hillary-clinton-defies-subpoena-wiped-her-server-clean-joel-gehrke)
And then after they found an archive of the emails after the subpeona, illegally destroyed the evidence AFTER it was evidence:
"On March 4, 2015, the House subpoenaed all emails from Clintonâ(TM)s personal servers, including a document preservation order.
PRN staff member X had a âoeconference call with President Clintonâ(TM)s staffâ on March 25, 2015, after which â" sometime between March 25th and 31st â" âoehe had an âoh shitâ(TM) moment,â when he realized he had forgotten to wipe clean the PRN server as he had been instructed to do by Mills in December 2014.
At some point during those six days, PRN wiped the server clean using BleachBit â" despite the subpoena from the House earlier in the same month.
In fact, PRN staff member X admitted to deleting the remaining emails despite being âoeaware of the existence of the preservation request and the fact that it meant he should not disturb Clintonâ(TM)s e-mail data on the PRN server.â" (http://thedailycoin.org/2016/09/04/clinton-email-server-wiped-after-her-subpoena/)
This is direct destruction of evidence and obstruction of justice, so naturally the FBI gave immunity deals to the people responsible, who then turned around and say Hill Dawg had nothing to do with it. It is fantastic (and I don't mean that in the good sense) how this investigation was conducted.
