If violence spreads like a disease, it can be interrupted. How a new team in Milwaukee is trying to stop one shooting leading to another.

The Office of Neighborhood Safety in Richmond, CA took a radical new approach to urban violence by creating mechanisms to financially stabilize perpetrators of violent acts in crime-ridden neighborhoods - essentially paying people not to kill. They have been dramatically successful at weening violent criminals off the destructive behavior by using a comprehensive approach that includes using solid data, employing mentors with similar backgrounds to the criminals, and monetary incentives.

Across the country, hospitals are embracing intensive intervention programs to help victims of violence — including those who have criminal histories — after they have been brought in for treatment of injuries. Such programs can help prevent retaliation, reduce the chance a patient will be violently injured again, and put people on track for success.

The Centre for the Prevention of Radicalization Leading to Violence in Quebec has expanded rapidly, becoming a model for programs around the world. What sets it apart from projects in Europe and the United States is that it confronts extremism of all stripes — not just Islamist — and focuses on behavior that signals the risk of violence, not just radical ideas, only involving law enforcement as a last resort.

In Mancos, Colorado, the school board voted “no” to arming school staff in the traditionally Western town. Across the United States, the question of arming teachers is being brought up as a response to the increase in school shootings. The policy is highly contested, with some saying it provides students with a feeling of safety, but others saying the risks associated are too high. For the Mancos community, such a vote is a surprise given the town’s gun-friendly history, but is explained by the increase in new residents.

Across New Hampshire, youth are leading the fight against substance abuse. Programs like Dover’s Youth-to-Youth, Stand Up Sachems, Youth Leadership Through Adventure, and the Making it Happen Coalition, are all youth-led, adult-supported initiatives that are empowering young adults to create and disseminate substance abuse awareness and prevention campaigns. Fundamental to each of these efforts effective communication and creating a sense of community as key to prevention.

DOROT is a non-profit organization that matches seniors with younger adult volunteers for social visits to combat isolation and loneliness and to promote intergenerational friendships. Many of the seniors are widowers and social isolation can lead to negative health consequences. The organization also delivers fresh meals and holds other events, but was unable to operate as usual once the Covid-19 pandemic hit, so DOROT helped seniors set up Zoom for online conferencing. The group has matched 500 seniors with volunteers and advises similar programs across the country. Many pairs have formed deep friendships.

Tennessee Reconnect, which started as a small-scale "mentorship and financial support program", has now been adopted and expanded throughout the state as a way to help adults start or continue higher education. Now in its second year, the program matches applicants with "navigators," adult mentors who understand the specific student's financial and social challenges and helps them navigate the process every step of the way. The program also provides funding to students to pay for coursework and is now looking to expand its operations to jails and prisons.

The South Central Leadership Academy was started in Los Angeles by a college student who believes that gun violence survivors like him should lead the community response in finding solutions to violence. Its first year of paying more than a dozen student survivors to learn community organizing skills succeeded in attracting funding to expand to Nashville, Baltimore, and Atlanta. COVID-19 put the latter two expansions on hold, but LA and Nashville continued with well-attended classes learning remotely. Founder Marco Vargas hopes to turn this startup into a national network of youth leadership academies.

Crime-tracking mobile apps give millions of Brazilians crowdsourced data on urban violence, alerting people to dangerous places and filling gaps in government data on shootings, robberies, and other risks. But apps such as Fogo Cruzado (“Crossfire”) and Onde Tem Tiroteio (“Where There's a Shooting”) offer statistically crude glimpses of crime, distorted by media and racial biases that one expert blames for myths about the risks people actually face.

Seven teen suicides in one county over a two-year span prompted residents whose lives were touched by suicide to form DeFeet, an educational and advocacy group devoted to the message that suicide is preventable. Thanks in part to its trainings, public speakers, support groups, public education campaigns, and advocacy for gun safety, local schools now screen all students for suicide risk starting in middle school. A local health clinic now screens all patients and credits DeFeet, named for its annual 5K memorial walk, with creating "an environment where we are not as afraid to talk about suicide."
