Trump said: "Let me just tell you before we go any further, in Chicago, which has the toughest gun control laws in the United States, probably you could say by far, they have more gun violence than any other city. So we have the toughest laws and you have tremendous gun violence."

Chicago officials dispute that their laws are the toughest, as Trump claimed, but either way: strict city laws are undercut by more lax laws elsewhere. To wit: A majority of Chicago’s illegal guns were first bought out of state.
