If you're comparing us to Britain, they're probably viewed as quite lax.

The current government has been talking about restricting certain firearms as well.

Yeah.

this moved quickly overnight, and there was at least initially the hope that this was a break in the case after 10 days of searching.

But then this man who was detained was released, and he did speak to reporters, including one of my CBS News colleagues.

We know that he was detained during a traffic stop in that border town.

He was initially described as a person of interest, and authorities spent hours searching his vehicle and his home.

But after he was released, he told one of my colleagues that he works as a delivery driver, but he has no idea why he was stopped and questioned and that he doesn't know anything at all about Nancy Guthrie.

In fact, he said he doesn't even know who Savannah Guthrie is and has never watched the Today Show, Charlotte.

Right.

And authorities have said, Charlotte, that they are finally making some progress in the case.

We see that in the form of that doorbell camera footage.

We know that they've also been scouring security cameras from Nancy Guthrie's neighborhood looking for any vehicles in the area at the time of her disappearance.

Perhaps that search is what led authorities to this traffic stop.

And as for that doorbell camera footage, initially authorities had thought that it had been overwritten or deleted, but they were able to work with the manufacturer to access those images.

It shows a person wearing a mask and gloves outside of her front door.

They're obviously trying to identify that person, hoping that somebody recognizes that individual, and they're asking for the public's help.

Well, it is being so closely followed.

Obviously, we're speaking with you at the BBC.

And here in the United States, it's leading newscasts on multiple networks.
