CHICAGO—Violent crimes—from homicides and rapes to robberies—have been on the rise in many major U.S. cities, yet experts can’t point to a single reason why and the jump isn’t enough to suggest there’s a trend.
Still, it is stumping law enforcement officials, who are seeking a way to combat the problem.
“It’s being reported on at local levels, but in my view, it’s not getting the attention at the national level it deserves,” FBI Director James Comey said recently. “I don’t know what the answer is, but holy cow, do we have a problem.”
Americans have grown accustomed to low crime rates since a peak in the 1990s. But law enforcement started seeing a spike last year that has continued unabated. What’s unusual, however, is that it’s not happening everywhere. Chicago and Los Angeles are seeing homicides on the rise, but other places like Miami and Oakland are not.
