Preliminary Police Procedures Review

A concise written assessment of whether the available evidence is consistent with applicable law, departmental policy, officer training, and generally accepted practice.

Typically requested early, before committing to a full expert analysis.

Professional Overview

I assist attorneys in evaluating police conduct in criminal, civil, and administrative matters involving law enforcement — analysis grounded in the available evidence, applicable law, departmental policy, and officer training.

Experience

A 26-year supervisory career spanning patrol operations, criminal and administrative investigations, policy compliance, and critical incident response — evaluating officer decision-making and compliance with departmental policy throughout. I now apply that same analytical approach in evaluating matters arising in litigation.
