A Denver Police shelter-in-place order for an active barricaded subject at 2495 South Vine Street, two blocks south of the University of Denver, was inadvertently broadcast as a Wireless Emergency Alert to most of metro Denver around 8:15 PM MST on January 17, 2026. DU Campus Safety pushed its own DU Alerts telling students to stay away from windows and doors, then clarified there was no active threat to campus.

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.
DU Alerts: SHELTER IN PLACE Stay away from windows and doors Active threat
Final assessment
All 25 reads agree the source is present; the branded DU Alerts tag identifies the University of Denver as the sender.
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.
Final assessment
Near-unanimous that the hazard is present; the alert names an active threat, with one read finding it too unspecific.
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.
Final assessment
All reads agree the location is absent; no building, area, or campus is named for the active threat.
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
Unanimous that guidance is present; recipients are told to shelter in place and stay away from windows and doors, protective actions.
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.
Final assessment
All 25 reads agree time is absent; no clock, date, or recency cue appears, and Active is part of the hazard, not a time.
When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.
Final assessment
Unanimous present; all 25 reads agree the alert conveys danger and its potential consequences.
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.
