Why do you think Obama has tasked the NIH with mapping every single neuron in the human brain and what it does?
In the future.
A hypothetical scenario may go like this.
Cop pulls you over for speeding, taillight, whatever...
Cop instructs you to get out of your car and place this “Cap” on your head.
He informs you that this is for your safety, as it will allow him to determine if you have violent intentions. If you don’t have violent intentions than all is good.
Your brain waves are then feed wirelessly and analyzed in real-time and the results are displayed on the Cops “Google Glass”.
In addition to virtually everywhere you have been, everybody you talk to, every group you are a member of, if you own a gun, if you have written statements about the threat of Government and on and on....
This “threat matrix” will then be matched to your “Current State of mind”.
If your current “State” is sanguine, you take your ticket and go.
If on the other hand you’re agitated, paranoid and even calculating, you are a threat.
“Future Crime” suspect that needs further evaluation for the good of society.
