On February, 22, 2019 at 11:55 p.m., the MIT Police responded to the Alpha Delta Phi fraternity located at 351 Massachusetts Avenue, Cambridge on a report of a burglary at that location. The reporting party advised Officers that he observed an individual standing on the first floor ledge of the building reaching in through an open window. When confronted by the reporting party, the suspect stated that he was attempting to retrieve his bag from that room. The suspect then fled on foot on Massachusetts Avenue in the direction of Central Square. The reporting party described the suspect as: Male, Black, 6'00", medium build, 50-60 years of age, wearing dark clothing and a navy blue stocking cap. Suggestions While victims of crimes are never to blame for criminal activity, there are some precautions that can be taken. In order to protect yourself and your belongings from theft and/or facilitate the recovery of your stolen property, MIT Police encourage you to follow these tips: - See Something - Say Something: Immediately notify the MIT Police at 617-253-1212 or 100 from any campus phone if you believe a crime is occurring, has occurred, or is about to occur. - Always lock your office and residential doors and windows. Assure that the locks are in good working order. - Lock your office door if you are leaving (even if only for a minute or two). - When entering or exiting an office, make sure the door closes tightly behind you. - Report suspicious people or activity. Report all tailgaters. The MIT Police want to remind the MIT community that we are located in an urban setting and share many of the crime and safety issues that exist in any city. The MIT Police are investigating this crime and request the assistance from the MIT community. If you wish to leave an anonymous tip please call 617-258-TIPS (8-8477). Issued by Sergeant David J.

Message elements

How the first alert is built

To check this alert, Claude Opus 5 (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardpresent25/25

    Final assessment

    Present, 25 of 25. The call was "on a report of a burglary", with a man seen "standing on the first floor ledge of the building reaching in through an open window".

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationpresent25/25

    Final assessment

    Present, 25 of 25. The scene is the "Alpha Delta Phi fraternity located at 351 Massachusetts Avenue, Cambridge", with the suspect fleeing toward Central Square.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

    Final assessment

    Present, 25 of 25. The Suggestions tell readers to "Always lock your office and residential doors and windows", to "Report all tailgaters" and to call 617-253-1212 immediately.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Impactabsent0/25

    Final assessment

    Absent, 0 of 25, with no dissent. The intruder "fled on foot on Massachusetts Avenue" after being confronted, and the notice names no theft, injury or continuing danger.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
