Each week, we review the week’s news, offering analysis about the most important developments in the tech industry.

Hello, Adam Satariano here. I cover technology in Europe for The New York Times.

This past week, as part of some research I have been doing about government uses of technology, I went to Berlin to attend the European Police Congress, an annual conference for law enforcement agencies.

When the conference started more than 20 years ago, the discussion was mainly about training techniques and other cop-on-the-beat-type work, said Uwe Proll, the main organizer. The companies there were predominantly selling guns, safety gear, radios and other equipment.

But as in every other industry, the conversation is now dominated by technology. At the panels I attended, and in conversations I had with attendees, the central topics were how to take advantage of artificial intelligence, data analytics, facial recognition and other emerging technologies.
