Martin Kaste

Martin Kaste is a correspondent on NPR's National desk. He covers law enforcement and privacy, as well as news from the Pacific Northwest.

In addition to general assignment reporting in the U.S., Kaste has contributed to NPR News coverage of major world events, including the 2010 earthquake in Haiti and the 2011 uprising in Libya.

Kaste has reported on the government's warrant-less wiretapping practices as well as the data-collection and analysis that go on behind the scenes in social media and other new media. His privacy reporting was cited in the U.S. Supreme Court's 2012 United States v. Jones ruling concerning GPS tracking.

Before moving to the West Coast, Kaste spent five years as NPR's reporter in South America. He covered the drug wars in Colombia, the financial meltdown in Argentina, the rise of Brazilian president Luiz Inacio "Lula" da Silva, Venezuela's Hugo Chavez, and the fall of Haiti's president Jean Bertrand Aristide. Throughout this assignment, Kaste covered the overthrow of five presidents in five years.

Prior to joining NPR in 2000, Kaste was a political reporter for Minnesota Public Radio in St. Paul for seven years.

Kaste is a graduate of Carleton College, in Northfield, Minnesota.

If you're murdered in America, there's a 1 in 3 chance that the police won't identify your killer.

To use the FBI's terminology, the national "clearance rate" for homicide today is 64.1 percent. Fifty years ago, it was more than 90 percent.

And that's worse than it sounds, because "clearance" doesn't equal conviction: It's just the term that police use to describe cases that end with an arrest, or in which a culprit is otherwise identified without the possibility of arrest — if the suspect has died, for example.

Violent crime in America has been falling for two decades. That's the good news. The bad news is, when crimes occur, they mostly go unpunished.

In fact, for most major crimes, police don't even make an arrest or identify a suspect. That's what police call "clearing" a crime; the "clearance rate" is the percentage of offenses cleared.

In 2013, the national clearance rate for homicide was 64 percent, and it's far lower for other violent offenses and property crimes.

A new statistical analysis by the Justice Department estimates that the government has been undercounting the number of people killed by police. As NPR's Martin Kaste reports, it's been undercounting those stats by half.

On Valentine's Day weekend, Jonathan Hutson found himself exchanging tweets with somebody unpleasant: a Holocaust-denying anti-Semite, by the look of things.

Then Hutson looked up the person's earlier tweets. This guy was tweeting about shooting up a school. He said that he wanted to execute 30-plus grade-school kids."

So Hutson decided to draw the person out — "engage with him," as he puts it — to see if the threats were real.
