Analyst Talk - David Grabelski - The Life Triangle
Episode: 00307 Released on February 23, 2026 Description: In this episode of Analyst Talk with Jason Elder, David Grabelski shares insights from a 55-year career spanning LAPD homicide, gang investigations, NDIC intelligence work, and teaching at Mercyhurst University. He discusses the early days of link analysis, visual investigative charting, and how analytical thinking shaped real-world investigations long before modern tools existed. David also introduces the “Life Triangle” of time, health, and wealth, and how it applies not only to career progression but to long-term professional sustainability. The conversation explores intelligence failures, the importance of broad experience over early specialization, and why skillsets matter more than tools in the evolving world of analysis. This episode is essential listening for analysts navigating career growth, technological change, and the balance between expertise, impact, and longevity in the profession.
