I'd be much less annoyed by these restrictions if the TSA did a better job explaining the reasons for them. Unfortunately, a statement such as, "Our scanners can't reliably tell the difference between batteries and specially-crafted explosives." is not something they want to publish. I have no idea if that's actually true, but it seems plausible.<p>Also, the implementation of this policy seems rather inconsistent. Are broken/powerless devices allowed in checked luggage? Can they be shipped via air freight? If I bring spare batteries, do I have to put them in a device and power it up? Etc.<p>Edit: It looks like this is a reaction to rumors of a plot to build bombs that look like laptops.[1]<p>1. <a href="http://abcnews.go.com/International/terrorists-team-syria-build-generation-bombs/story?id=24274983" rel="nofollow">http://abcnews.go.com/International/terrorists-team-syria-bu...</a>
