First, 15,000 emails where not all of the sudden "Found". The FBI looked at them, found nothing. A lawsuit by the right-wing funded "Judicial Watch" asked that they be released to the public and the Judge in the case agreed. Nothing new there. This email thing is so bogus from the start. Lets geek out for a moment; Email servers circa 2008-2009 were transitioning from a Novel/sendmail/procmail based system to MS-Exchange. People that used Exchange were hooked and liked it; the contacts, the calendar system, attachment handling were just superior. The word is that State department email just wasn't good at handling all of that like exchange, so it was common to setup alternative email routes. So have your smart IT guys set up a server running EXCHANGE and your productivity increases 20 fold! Of course being security conscious, you can't just put the Sec. of State on the cloud! Security-wise she was Sec of State married to a former President, so what would be more secure than to run the server from her home? Which is more secure; Collin Powell using AOL or Clinton running her own email server?
Basically this is all just a bunch of crap made up by right-wing dicks making political noise during an election year. It's typical Dirty Tricks from a party that is made up of A-holes.
