If you’ve wandered onto social media in the last week, chances are good that an algorithm seemingly designed to reward snuff films served you a video of a gruesome killing. Among the clips is footage of 23-year-old Iryna Zarutska being brutally, fatally stabbed on the Charlotte Light Rail by Decarlos Brown Jr., who faces both a first-degree murder charge and a federal charge for committing an act of death on a mass transit system.

Over the past few days, the right has sought to capitalize on Zarutska’s horrific murder, arguing that Democrat-controlled cities are hotbeds of violence and lawlessness and using it as further evidence of the wisdom of the Trump administration’s decision to dispatch National Guard troops to Los Angeles, Washington D.C., Chicago, and Boston in the name of law and order. In the case of the murder in Charlotte, the right has zeroed in on a particular target: public transit. “The problem is a lot of people, unlike the rich liberals, they can’t ride Uber, they don’t have a vehicle, they have to take public transportation, and public transportation has become an epidemic of violence and homelessness across the country,” Transportation Secretary Sean Duffy told Fox News’s Sean Hannity. Those same liberals, Duffy said, “hate cars” and “want us all to ride public transportation.”

Duffy’s argument isn’t subtle: Use mass transit, and you’ll get yourself killed. There’s just one problem: He couldn’t be more wrong. According to one recent study, car travel is 10 times as deadly as travel by mass transit. Another report from the nonprofit National Safety Council finds that, for every 100 million miles traveled by passengers, rates of car deaths were 17 times greater than deaths from train travel, and 50 times greater than deaths from bus travel.
