July 28th, 2025, 6:28 PM. A 27-year-old man double-parks a black BMW on Park Avenue between 51st and 52nd Streets in Manhattan, walks into the public plaza carrying an AR-15, and opens fire at the entrance of 345 Park Avenue—home to the NFL headquarters, Blackstone Group (one of the world's largest investment firms), and Ruben Management.

Four people dead. Including the shooter. All in under 90 seconds.

The building's surveillance system flagged him as a potential threat at 6:27 PM—60 seconds before the first shot. The cameras captured him crossing the plaza with a rifle in broad daylight. Sixty seconds of advance warning.

In this episode, I break down:

The 60-second window between detection and disaster

What "response plans" and "capability plans" actually mean when seconds count

Why you can't protect against everything.

This case will discuss how we think about workplace security, building access, and threat response for years to come.
