Once a mind-reading machine is perfected and universally used, we shall have adequate security.
And now that I'm on the subject of such technology, we might get back to the original thread subject (The Candidates -- remember?) of political candidates. Let's throw in incumbents and well-known captains of industry as well. Vocal lie detectors have been around for quite some time. Anyone can buy such software.
So why don't counterculture TV and radio stations employ such during a candidate's or incumbent's speech or news conference? Yeah, you might say of someone you dislike, as long as his lips are moving you know he's lying, but wouldn't you like to have some objective evidence? I couldn't be the only one who's thought of this.
