Back in November of 2000, I wrongly brought my laptop into work during the hanging chad affair, connected to the internet via the phone system, and got brought up on charges, and fined $5,000. I should just have committed treason and I'd have gotten away with it.
Back around 2008 or so, I was working in a secure area of the Pentagon when a Butter-bar Lieutenant brought his brand-new laptop in and fired it up. I was on the security detail that discovered this. We snatched that computer up and hauled it out of the area faster than you can say Hillary's liquor cabinet. He followed us down the hall where it got tossed into the maws of a grinder. It was turned into dust. Poor sap.
