Let's sit back and take a chill pill. Will this capability exist? Yes, probably. Am I concerned that this capability will be deployed against me? No, not really. Theoretically it could, but then again, so could a dude with a gun. I live in a democratic first-world country, the capabilities of my own government are likely to exceed the capabilities of those who want to kill me. And theoretically maybe my government might want to kill me... but it could already do that anyway, using a dude with a gun.
