Why Detroit Might Be the True Test of Whether More Cameras Make Cities Safer

What if a computer program could tell you who was at risk for shooting someone or being shot themselves? This is now a reality for Chicago Police Department. By piloting the use of this technology, and assembly a cohort of cops, social workers, ministers and moms to visit the names of those the computer names, the city has seen a decrease in violence over the last year.

In the first half of a six-month experiment, Baltimore's "wide-area surveillance" using video cameras flying above city streets to aid in crime investigations has led to only one arrest. The city's police commissioner doubts the city will agree to pay for the surveillance once private funding for the pilot project runs out, but he says he'll know more after the six-month experiment. The experiment is aimed at Baltimore's high rates of gun violence. Besides its effectiveness, critics worry about its privacy implications and that it targets mostly Black neighborhoods.

After charged discussions and protests around racial injustice within police departments, Baltimore set out to find a solution to bridge the divide created between the city's police force and the kids that lived in stereotyped neighborhoods. Using nature as a common ground, the Outward Bound Police Youth Challenge was born to bring the two sides together and teach them that they have more in common than they may think.

Genetic genealogy's use in criminal cases has gone mainstream. As the cases of three murder victims in Indiana illustrate, the science of DNA evidence combined with genealogical research and detective work is rapidly ramping up, from a hobby to a curiosity and now to a major commercial and criminal-justice opportunity. Hundreds of missing persons have been identified from decades-old remains, or murder suspects identified from old biological evidence in cold cases. By creating a family tree of the victim or suspect, investigators can zero in on an identity more quickly and inexpensively than ever.

Two years after reorganizing a police gun-enforcement unit to focus it on an evidence-based approach to preventing retaliatory shootings, Portland city leaders abolished the unit in a round of police budget cuts and failed to reinvest that money in community-based alternatives that don't rely on the police. The result, criminologists say, is a worst-case scenario: a policing reform that creates a vacuum and could be to blame for an alarming spike in gun violence. The most effective solutions, they say, blend effective policing with proven community-based programs.

A drone program has helped the small town of Linn find missing people, rescue people in medical distress, and find multiple drowning victims in the town's lake. Police now spend less time conducting searches and have saved lives with their eye in the sky. By carefully developing policies and by practicing transparency, making flight logs public, the town has eased privacy concerns and earned enough community support to pay for the latest drones with donations.

After two failed attempts, Oakland Ceasefire retooled its approach and since 2013 has been a significant factor in lowering homicides and nonfatal shootings. The program, used in various ways in many cities, identifies young men at high risk of getting shot or shooting others and then offers them life coaching and social services to keep them out of trouble. By de-emphasizing the role of police, pinpointing those most in need of help, boosting community involvement, and forming deeper personal relationships, the program is credited with a 32% reduction in gun homicides over a six-year study.

A space-based initiative called Global Fishing Watch is using satellite imagery and data to hold companies accountable to their promise of providing sustainable sourced seafood. While the volume of data and cost of obtaining it can be a challenge, the organization has partnered with key collaborators to help with the effort. Countries like Indonesia and Panama are working with them to stop illegal fishing.

Chicago suffers from violence and tension between police officers and low-income predominantly Black communities. In 2011, the chief of police consulted with a network of university academics and began implementing “procedural justice,” which was an approach that trained police departments to surmount the lack of confidence that residents felt towards officers. The academics and police chief found that by directing social workers to the homes of at-risk community members, and regarding them with respect, there was a reduction in violence—but now the program has stalled.

Researchers trained Tucson police officers in procedural justice, which involves treating people with dignity and respect by giving them a voice and showing neutrality, to help them de-escalate situations with fewer arrests and less violence while building trust in the community.
