Polygraph evidence is not admissible in Maryland courts. See State v. Hawkins, 604 A.2d 489 (1992).
UPDATE—I see from A Reader’s comment that the Cabin Boy is accusing me of stalking his Twitter timeline because I took a look at his Twitter feed based on a phone tip from a friend and found the amazingly stupid tweet above. Given that this post went up at 5:39 pm and A Reader’s comment is timestamped at 5:55 pm, it would seem that the Cabin Boy follows this website closely enough to allow him to react to my posts within a quarter-hour. So who is cyberstalking whom?
