Scientists Have Found a Way to Photograph People Through Walls Using WiFi

WiFi can pass through walls.

This fact is easy to take for granted, yet it’s the reason we can surf the web using a wireless router located in another room.

However, not all of that microwave radiation makes it to or from our phones, tablets, and laptops. Routers scatter and bounce their signal off objects, illuminating our homes and offices like invisible light bulbs.

Now, German scientists have found a way to exploit this property to take holograms, or 3D photographs, of objects inside of a room — from outside of the room.

Funny. That's the first thing I thought of when I saw this. Sad part is, I remember seeing those ads in Popular Mechanics and other magazines way back when.

Just because your paranoid, doesn't mean they're not really out to get you.

If you are trying to find out how many terrorists are inside, they are bound to notice you walking around the building with your antenna. And they have to be cooperative and remain stationary the whole time.

(Actually, flying a drone around the building might not be a bad idea.)

'Stationary' pretty much describes Congress. 'Domestic terrorists' seems to as well. A drone would probably go apeshit there.

Is "Congress" the new definition of "Domestic Terrorist" ? Sounds about right!
