Cameras and phone surveillance and miniature microphones are also new. When technology encroaches upon privacy, "that's just the way things are!", but when it protects it, "it's new and different and must be restricted!".

More to your point, I do think law enforcement should be allowed to spy on people when necessary (by whatever definition of 'necessary'). But that's a far cry from saying that people should be compelled to assist in the spying.

There's no warrant to compel someone to knowingly carry a bug.
