Since 1960, U.S. homicide rates have been falling—that is, until this year.

Taken together, it paints a bleak picture for Americans’ safety, and it has violence prevention scholars trying to figure out what led to the changes—and when. At the annual meeting of the Major Cities Chiefs Association on Monday, police chiefs grappled with the fact that some cities are seeing a 50% increase in murders compared with last year.
