Research Article 2

I think this was a good article because it was sort of interesting to see that something that was made to be somewhat indestructible, could be broken. I do not understand why they put this information out to the public because it could be used in a murder case or just a regualr trial where they are using this method to figure out whether the defendent was guilty or not. What does moving those certain fingers and one toe do to make the test unrelyable? Why did the people who can up with this way of cheating around the test use those three body parts? What do they connect to, that reduces the activity in the front-most part of the brain to show whether they are lying or telling the truth. What is it that calms you down by doing those three movements with those three body parts?
