In a letter to the Tech, Executive VP and Treasurer Israel Ruiz writes:
One minute into the communication, the caller reported someone with a "really big gun," and "armor" who was "getting out of control." The CPD dispatcher immediately sent CPD units and State Police to the site, and notified MIT Police.
Ruiz also writes that while police responded very well to the perceived threat, they should have alerted the MIT community earlier than 90 minutes into the incident that something might be happening.
