Dick's Sporting Goods overhauled its gun policies after Parkland. The CEO didn't stop there.

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.

Despite advancements in technology in most sectors of life leading to an increase to access of information about practically anything, little is still known about the ocean and its behavioral patterns. Liquid Robotics – a Silicon Valley-based company – is trying to change that. Engineers here have created the "Wave Glider," which essentially acts as a router within the ocean powered by wave energy and solar panels. This invention can transmit data on tectonic activity that has the potential to predict tsunamis.

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.

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."

Advance Peace mentors young people at risk of committing or suffering gun violence, guiding them through a "life map" process to exit street life and set goals for a safer, healthier future. The program, which started in Richmond and has expanded to other cities in California and beyond, contributed to a 22% decrease in gun homicides and assaults in an 18-month period. The decrease was 39% in the first targeted neighborhood. Mentoring includes linking youth to cognitive behavioral therapy, jobs, and field trips to expand their experiences. When they meet certain goals, they get paid a "life map allowance."

Domestic abuse of the staff in the households of the 1% is often overlooked or ignored. But foreign missions in the US that abuse their domestic staff are finally being held accountable.
