This post by Wil Wheaton is a really great reminder that when you are traveling, and I wouldn’t necessarily just put this as international to Britain but even when visiting the next town or crossing state lines even. Rights are being trampled everywhere you go, wether it be from a out-of-control cop, a bloodthirsty Sheriffs deputy or even a sticky-fingered TSA agent there is no lack of potential thugs, enemies, and thieves in your midst.
There are ways to secure your data and keep it handy as well. Store everything in an encrypted disk image or TrueCrypt archive on a cloud service like Dropbox or Google Drive and duplicate the same things in your memory sticks. If the thugs take your devices then you can rest assured that all you lost was the material itself, but no content.
I’m surprised that journalists and people who know journalists don’t all use GPG to secure their communications. I would think that if you were a whistleblower or had contact with a whistleblower that these little checkboxes would be foremost on your mind and already checked off.
You can’t trust any government, any cop, or any Vampire to keep their word. This goes for everyone as well, including your carrier and service providers. What should Verizon know? Shit. How about Dropbox? The same. Trust nobody and you’ll be safer than someone who trusted someone else. Trust is earned and right now, very very few people have it.
