What a terribly written article, it almost makes me wonder if it is AI. Not that I expected a well informed article on US gun law from the BBC. Even the grammar is awful, the following phrase is formatted as a paragraph:

“Around 80,000 licensed firearms dealers in the US who are already required to conduct background checks.”

Not to mention it’s full of generally bad information and as you pointed out they failed to capture the miniscule scope of what this change will actually accomplish.
