President Trump?

It is a great pleasure for me as well.

And it feels very warm seeing you again because it's been many years.

It is normal for the two leading economies of the world to have frictions now and then.

Mr. President, I'm ready to continue working with you.

This is The Guardian.

Today, coming to a store near you, the rise of live facial recognition.

These stories sound like they happened in the same place, but they didn't.

They're three different shoppers in three different parts of the UK, all flagged by AI systems they didn't even know were watching them.

And it could be happening to you too.

Every time you walk into a supermarket or down the street...

Live facial recognition is being hailed as a powerful new frontier in the fight against crime.

Not just by police, but private companies too.

And as it spreads, it will expand surveillance into more and more public spaces.

And the problem is, it doesn't always get it right.

From The Guardian, I'm Annie Kelly.
