"I don't think they can do X-Ray machines because it requires an intrusion of particles on their part. But they can do heat, light, etc. because heat for example comes out of your body and home on its own and becomes open game. Sort of like garbage on the curb is abandoned property. Your heat signatures are essentially abandoned property."
See: NSA's TEMPEST. You'd be shocked and amazed what you can tell about what's going on inside a person's home just from the patterns of electromagnetic interference generated.

NSA's TEMPEST. You'd be shocked and amazed what you can tell about what's going on inside a person's home just from the patterns of electromagnetic interference generated. Even better, some people recently figured out how to tell what you're typing by the sound the keyboard makes. They only need to know who manufactured your keyboard and point a sound-detecting laser at your window.
