Agencies tout very high success rates, but some experts compare it to “crime control theatre”

On Sunday, March 22 of this year, a large swath of the population in Quebec was woken up at 4:25 a.m. as cellphones lit up and screamed. An Amber alert had been broadcast. Less than four hours later, the two missing children were thankfully found, unharmed, and the alert was cancelled.

Amber alerts cast wide nets in an effort to find abducted children and teenagers, but each time one is transmitted in Canada, we go through a predictable cycle. Many complain that these alerts cannot be turned off or muted, even in sleep mode, and that waking people up in the middle of the night to help them find a specific car that was last spotted 200 kilometres away is unnecessarily disruptive—with some even calling 911 to complain. Meanwhile, law enforcement officials remind us through the media that these alerts are only used when necessary and that they save lives.

Any subject tied to the safety of children is bound to evoke the deepest emotions. In fact, the crime that led to the creation of Amber alerts—and to their name—was monstrous enough that it’s no wonder it rallied influential people into building a system that could potentially prevent this kind of crime.

But warranted emotions aside, do Amber alerts even work? What little data we do have point to a system that has likely been oversold to us.
