The city of Charlotte is contending with another stabbing on its light rail system, months after the fatal stabbing of a Ukrainian refugee served as a flashpoint for the crime debate in major American cities. The stabbing on Friday, which left one person seriously injured, happened on Charlotte's LYNX Blue Line – the same route where refugee Iryna Zarutska was killed. The Trump administration and conservative politicians cited her death as an example of the violent crime they say plagues many Democrat-led cities across the United States.
