text: The law has trouble with telling when someone is lying or even when they are telling the truth. I believe that the Facial Action Coding System could help solve this problem. Acorrding to the paragraph, the Facial Action Coding System can calculate the percent of the certain facial expressions that you are making. Which we all know that when most people lie, they make a certain facial expression or they act a certain way. If police and judges were able to use this sofwear they would be able to tell when someone is liying, and when someone is telling the truth. They could use the Facail Action Coding System as a lie detector. Doing this could help reduce crime rate, and it could help lock away people that deserve to be put in jail rather than innocent people.
