How the first alert is built
To check this alert, Claude (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.
Clery Crime Alert Burglaries The Department of Public Safety has been informed of three burglaries that occurred between August 2, 2025, at 11:47pm and August 4, 2025, at 8:08pm and 8:20pm at 521 West 111 Street, 420 West 119 Street and 500 West 122 Street, respectively. It is believed that these burglaries were all perpetrated by the same person. A video review shows an individual pressing intercom buttons randomly until they are let in. This technique is used at all three buildings. The individual is described as male presenting, with a dark complexion, black hair and a black moustache and beard.

Locationpresent25/25
Final assessment
Consensus that three West Side street addresses fully answer where.

Impactabsent5/25
Final assessment
Majority finds impact absent; a minority reads Clery serious or continuous threat as severity, but the body lacks harm-to-people consequence language.
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.
