Excerpt of Judge's Ruling in the Circuit Court of the City of Alexandria, Virginia:

"In my opinion Mr. Tynan's testimony, and that of his associates, seemed to be very professional and very exact. His methods are very impressive. Using the word Detective may be inappropriate, but this investigator or Private Investigator, had prior police experience, and his testimony evidences that."

"I find him to be very credible. I think I have a duty to make that observation, since I saw him and have evaluated his testimony and his demeanor and the manner in which he testified. His techniques are very professional."

"I reaffirm my position that Mr. Tynan, the investigator, was a very impressive witness, and I must say that in the light of caution with which courts review the testimony of a paid investigator. The man was very professional, more so than most investigators that I've ever heard testify in court, including police. He is a former policeman, a very impressive witness."

- The Honorable Judge
James L. Berry
