A shocking incident on board the light rail in Charlotte, North Carolina, in which a Ukrainian refugee was fatally stabbed and the suspect has a lengthy rap sheet, has once again put the spotlight on violent crime in cities and President Donald Trump’s plans to use the federal government to counter it.

What happened

The unprompted attack happened shortly before 10 p.m. on Aug. 22. The victim, Iryna Zarutska, was a refugee from Ukraine. Court documents with a video of the attack showed Zarutska entering the light rail train car and sitting down directly in front of the suspect.
