Just make sure your stuff is encrypted and turned off. There's a 99.99% chance TSA doesn't give a fuarrrk about you and doesn't want to sniff your stuff. And even if they do, they can't force you to hand over your encryption keys without reasonable cause, in which case you're probably a terrorist and don't belong on Lainchan, or you're a VIP in which case you should be asking your secretary to find this out for you.
I've been through TSA dozens of times without any sort of incident or even them searching my laptop. I just bring it in my carry-on and mess around with my Linux install on the plane, reading all of the different man pages and learning about the kernel and stuff. (I'm a jew so I don't fly on planes with WiFi)
>>3966 Oh, and when I say turned off, I Just mean while you're going through the security check. The reasoning being that if you ARE actually an important person or they have reason to search you, your laptop will have the encryption keys stored in RAM when it's on, meaning it's vulnerable to having the RAM frozen and dissected by a CERT group.
