And for more on that Russian pipeline that President Trump was talking about, we turn now to NPR's Martin Kaste in Berlin. Hey there, Martin.

MARTIN KASTE, BYLINE: Good afternoon.

Police have always relied on data — whether push pins tracking crimes on a map, mug shot cards, or intelligence files on repeat offenders. The problem with all that information is that it has traditionally been slow and hard to use.

In the wake of the Parkland high school massacre, there's been renewed interest in "red flag" laws, which allow courts and police to temporarily remove guns from people perceived to pose a threat.

The new research offers insight into the laws' effect — and it may not be what you think.

"Although these laws tended to be enacted after mass shooting events, in practice, they tend to be enforced primarily for suicide prevention," says Aaron Kivisto, a clinical psychologist with the University of Indianapolis who studies gun violence prevention.

On a big-sky plateau on the eastern slope of the Cascades, a 10-acre parcel of land has been trashed by illicit pot farmers. Abandoned equipment rusts and jugs of chemicals molder.

Marijuana legalization wasn't supposed to look like this.

Five years into its experiment with legal, regulated cannabis, Washington state is finding that pot still attracts criminals.

You've seen it in the movies for years: Security cameras find a face in a crowd, and — Enhance! — a computer comes up with a name. In real life, facial recognition was too error-prone to work that quickly, especially with live video streams.

But now the Hollywood fantasy is coming true.

The dramatic videos of the shooting of Stephon Clark in Sacramento last month have rekindled anger over police shootings of unarmed people, often African-Americans. Many see the Sacramento shooting as a sign that little has changed in the way American police use deadly force, despite years of protests and media attention since the shooting of Michael Brown in Ferguson, Mo., in 2014.
