    Will the New 988 Hotline Be a Game Changer for Mental Health or a Missed Opportunity?

    Someone dies from suicide in the United States every 11 minutes, a rate that has increased almost 30 percent since 2000. The 988 mental health hotline will launch on July 16, but states need to clear significant hurdles: funding the expanded crisis response system and making sure people know it's available.

    Investing in policy-focused research can be among the ways foundations catalyze change. Impactful work may involve strong collaborations across funders, researchers, and community partners. And it may require flexibility in design and execution as well as a commitment to getting the findings into the hands of decisionmakers who can use the findings to create change.

    Elevating Equity in Los Angeles Juvenile and Criminal Justice Reform

    At age 13, Black children are placed in juvenile detention at nearly 3.5 times the rate of white children. By age 17, that ratio increases to 4.5 to 1. And the trend continues into adulthood. Without ongoing attention and deliberate policies and programs, injustices are likely to persist.

    Defund the LAPD? Garcetti Budget Proposal Takes a Step in That Direction

    Calls to “defund the police” have grown common and urgent in the wake of police killings of George Floyd, Breonna Taylor, and numerous other Black Americans. Research and community activists agree: Public safety can be improved by investing more public dollars in a social safety net, and less in policing and incarceration, in Los Angeles.
