Taz,

You are afraid because you are an honest person. You know that counter measures go beyond your moral and ethical principles, and just thinking about using counter measures disturb you. There is no need to worry if you tell the truth. Two and a half years will not even put a dent in the honesty that has been instilled in you, over a lifetime by your parents. Tell the truth, and pass the polygraph examination with flying colors. I guarantee your next post on this site will shock most readers.
