Denver Schools Make Weapon-Detecting K-9 Program Official

Live Poll

Should your local public schools use weapon-detecting dogs at school events?

Denver Public Schools introduced weapon-detecting K-9s to campuses through a pilot program last school year, and the partnership with Phantom K9 is now official. The dogs are trained to detect weapons and explosives and work at school functions across the district.

Why it matters

The district said the dogs provide an extra layer of safety at large events such as sports games. The decision to make the program long-standing followed a positive response from students and staff.

Phantom K9 has nine dogs that work school functions, and the district may deploy two to four at any event. In a simulation, the dog Cash alerted his handler to a hidden substance in less than one minute, though the district has not released outcome data on the program.

The players

Denver Public Schools

Denver Public Schools is the large urban public school district serving the city of Denver, Colorado.

Phantom K9

Phantom K9 is a private company that trains and operates weapon- and explosive-detecting dogs for schools and events.

The details

The dogs work entrances and exits and sweep crowds at events, pinpointing a firearm or contraband on an individual within a large crowd. They add a layer of security on top of police staff and offer a less intimidating alternative to metal detectors or bag checks. All Phantom K9 dogs are temperament tested, and during Saturday's recertification training a dog named Cash found hidden bags containing black powder.

Season Trajectory

Trained detection dogs have long been used by police and at large venues to screen for explosives and firearms. Denver's move extends that established practice into K-12 school campuses as a recurring safety measure.

Parents and students in Denver Public Schools may see trained dogs at entrances and exits and at school events. The district says the dogs are a less intimidating alternative to metal detectors and bag checks.

The takeaway

Trained detection dogs can screen crowds quickly, but the district has not published outcome data, so their long-term value at schools remains to be measured.
