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.

During the campaign, Donald Trump railed against "sanctuary cities" — generally understood to be jurisdictions where local law enforcement doesn't cooperate sufficiently with federal immigration authorities. Sanctuary cities were an especially hot issue because of the death of Kate Steinle, a tourist shot by a Mexican national in San Francisco in 2015.

Many police officers are warmly welcoming the election of Donald Trump, believing he'll defend against what many officers see as growing anti-police sentiment.

Trump was endorsed by the National Fraternal Order of Police, the largest organization of rank-and-file cops, and Executive Director Jim Pasco says that support was enthusiastic.

Gun control has been a minor theme of this year's presidential election, as Hillary Clinton promises to close "loopholes" in the background checks for gun purchasers, and Donald Trump pledges "unwavering support" for the Second Amendment.

The real battle over guns, though, has been waged at the state level this year — with a new emphasis on ballot initiatives.

What's striking about all the controversial police videos we've covered is how different they can look to people, depending on their backgrounds. If you're a police officer, certain things might stand out, while if you're a civilian or you've been arrested by a police officer, other things might catch your attention.

So we thought we'd try something new, using a video brought to our attention by member station WFDD in the Triad region of North Carolina. The recordings come from the body cameras of two officers as they make a routine call — which then goes bad.

Law enforcement is increasingly worried about losing access to powerful tools for searching social media because of changing attitudes at the social media companies that allow the searches.

Americans are seeing more homeless camps, especially on the West Coast. A number of cities there have declared emergencies over the problem, and as they struggle to find solutions, an angry debate has broken out about how much tolerance should be shown to illegal camps that crop up in public spaces.

The shooting of Keith Lamont Scott, a 43-year-old African-American man, by Charlotte, N.C., police is under investigation and the circumstances are very much in dispute, but when you listen to protesters, you hear that their frustration isn't about just this one case.

In the aftermath of the Sept. 11 attacks, many beloved public spaces were abruptly closed or had their access severely restricted. At the time, the public generally resigned itself to the new restrictions as a necessary evil in a time of war.

Fifteen years later, the public has stopped noticing. In some cases, such as scenic overlooks at certain dams, the government spent millions on new roads and bridges to allow the public access from less risky positions. But in other places, the restrictions remain, and it's the public space itself that has faded from view.

When should police be able to deactivate your social media account?

The question is becoming more urgent, as people use real-time connections in the middle of critical incidents involving law enforcement.

In the case of Korryn Gaines in Baltimore County, Md., earlier this month, police said that a suspect actively using a social media connection makes a standoff worse.

On Sunday, in the hours after the attack on officers in Baton Rouge, La., police reformers were quick to condemn the killings — and there were touching efforts to bridge the divide between the black community and police, such as a cookout in Wichita, Kan. Planned as a protest, it was repurposed as a community barbecue with local police.

The recent targeted attacks on police in Dallas and Baton Rouge have law enforcement on edge. Some departments are telling officers to patrol in pairs when possible, and to be extra vigilant about possible ambush.

Complicating matters is the question of how to interpret and react to the presence of a gun. With more Americans now exercising their legal right to carry firearms, police find themselves having to make rapid judgments about whether an armed citizen is a threat.

When you listen to the protesters, the message is clear: They think police are too quick to pull the trigger when faced with potential danger.

The reality is that it's very difficult to tell whether this is something that's changing: The statistics on police use of force in the U.S. are too unreliable to say anything for certain.

Investigators say a young African-American man named Micah Xavier Johnson was the sole attacker in Dallas Thursday night, when he shot 12 police officers, killing five. The attack came at the end of an otherwise peaceful march protesting police shootings.

Future Shock by Alvin Toffler was a huge sensation when it was published in 1970. The book perfectly captured the angst of that time and prepared society for more changes to come. Toffler died on Monday at the age of 87. This story originally aired on July 26, 2010, on All Things Considered.

When cities settle cases of inappropriate or illegal force by police officers, they pay — a lot. Chicago alone has paid out more than half a billion dollars since 2004.

Yet some advocates say all those payouts haven't had much of an effect on policing practices.

The horrific attack at a gay nightclub in Orlando, Fla., has captured the nation's attention, but the great majority of homicides are not due to mass shootings.

And in the last year or so, the murder rate has jumped in America's big cities.

"We are in the midst of a very abrupt, precipitous and large crime increase," says Richard Rosenfeld, a respected criminologist at the University of Missouri-St. Louis. He is the author of a study released Wednesday by the Justice Department examining reasons for the increase.
