Eye contact is important but you can't tell if someone is lying or not by lookin in there eyes anyway.

Just because you don't keep eye contact with a cop it don't mean your lying but he would probly think you are anyway. I mean i would probly keep eye contact with a cop even if i was lying and everyone knows to look someone in there eye if you don't want them to think your lying but the cop must know that so either way unless the story is real good he would think you were lying right, eye contact or not? But eye contact deffently looks alot better then none in any situation.
