Firm Philosphy

( beyond The Thin Blue Line )

The phrase The Thin Blue Line refers to the men and women in law enforcement: the police and the prosecutors. They stand between anarchy and the people they are sworn to serve and protect. The phrase infers the struggle for truth and justice.

In the the context of private matters, The Thin Blue Line cannot help. Law enforcement cannot help because of the volume of matters with which they must deal and beacuse of their public sector missions. Therefore, we at the firm provide help for clients beyond The Thin Blue Line. We strive to give the business and legal communities their chance to sort the truth from the deception. Our mission is to give our clients an opportunity to prevail, a shot at justice.

The firm's mission grew out of Jack's twenty-three year law enforcement career and his perception of what clients need. Symbolic of that mission and as a reminder to himself and the staff, he chose to have the firm letterhead, business cards, etc. display a thin blue line below the firm name. He wished to convey the idea that the firm goes beyond the thin blue line to meet the client's needs. By extension, we use an expression to address the spirit of the mission. We must 'Dream the dream for the client'. We try to imagine what will be helpful and then strive to find it.

The firm utilizes ten investgiative techniques to find that which will be helpful:

  • Research Backgrounds
  • Search for Assets
  • Interview & Interrogate Persons
  • Direct Undercover Operations
  • Identify & Locate Witnesses
  • Analyze Account Records
  • Trace Funds
  • Preserve Digital/Physical Evidence
  • Develop Confidential Sources
  • Conduct Surveillance Efforts
