Well, to be fair, he was talking about crime in the US only and gun control. But the sources that I have seen refute that claim too. It is not as simple as he says. There are some very low gun control states, such as Maine that have low homicide rates, but then there are states with much stronger gun control that also have very low homicide rates. But the states with the highest homicide rates also tend to have lower gun control. In the graph I posted the top four homicide rate states had one state with 3 stars, meaning moderate gun control, one state with 4 stars meaning low gun control, and two states with 5 stars, meaning almost no gun control. His claim does not hold up when one looks at the entire country. He did what so many people do to "prove" that he was right. He cherry picked one example.
