Dog gone it, nonombre, you finally cut through the fog on one point. You believe that you catch a vast majority. You should believe in what you're doing. Otherwise you're just satisfied with drawing a paycheck. However you didn't touch the other questions. Importantly, your problem with this site. Do you really think the info herein contained is useful to a criminal? If I was confident in my ability I would enjoy my "catch'em & wreck'em workshop. I would say send'em on down. On the other hand if I believed the info was useful enough to beat me even 20% of the time, as a polygrapher I would be worried to hell and back. I would request to go back the beat. I just can't tolerate 80% efficiency from me or anyone else. And when it comes to wrecking some innocent person's job opportunity --- hell I won't even go there now. It's almost my bedtime.
