Questions people ask
Grouped by who is asking. Anything not here, ask John directly.
I'm an attorney
Do you work criminal defense, including capital cases?
Yes. John is a court-approved Capital Crimes Defense Investigator. He is retained by defense counsel with judicial authorization and supports appointed counsel in the most serious cases, homicide included. He also handles criminal and civil investigations and litigation support for private firms.
Can you testify as an expert witness, and on what?
Yes. John provides expert witness analysis on investigative standards and protocols, private sector use of force, detention and arrest authority for private personnel, the legality and ethics of surveillance, and corporate and workplace security procedures. He is a published author on covert surveillance law and a certified instructor at the academy, college and university levels.
What does your report look like?
It is written to be used in court. In John's words, a report should explain why the investigator was present, what was observed, how the observations were documented and why they matter to the objective. "Nothing more. Nothing less." Findings are documented with methods meant to be admissible and defensible.
Do you locate and interview witnesses?
Yes. Locating individuals and interviewing witnesses are core parts of his litigation support, along with evidence collection, asset identification and background research.
Do you serve process?

Is your surveillance legal, and will it hold up?
That is the whole point of how John works. Every assignment starts with a legal review of recording, privacy, photography and trespass rules, because evidence that can't be used is worth nothing to a claims team. He literally wrote a book on the legal guidelines for covert surveillance in the private sector.
