'Lone Wolf' Killers Hard To Catch A lone wolf is what the FBI calls a killer who comes out of nowhere, with no links to terrorist or extremist groups. Trying to stop a lone wolf attack — such as the recent deadly shooting at the Holocaust museum — requires a mix of good luck and foresight.

MELISSA BLOCK, host:

In the last few weeks, there have been three high profile fatal shootings in this country inspired by religious, racial, or political hatred. The murder of a security guard at the Holocaust Memorial Museum here in Washington, D.C.; the killing of a doctor who performed late abortions in Wichita, Kansas; and the murder of a soldier outside an Army recruiting station in Arkansas.

As NPR's Dina Temple-Raston reports, plots like these are hard to stop.

DINA TEMPLE-RASTON: As much as law enforcement would have loved to have been lying in wait for suspect James von Brunn outside the Holocaust Museum earlier this month, there are limits to how much they can do.

Mr. CLINT VAN ZANDT (Former Profiler, FBI): If a person, though, makes a decision, I'm going to do it on my own. I'm going to tell no one. I'm going to leave no telltale emotional and psychological fingerprints anywhere around, that is very hard to frustrate, very hard to stop.

TEMPLE-RASTON: That's former FBI behaviorialist, Clint van Zandt.

Mr. VAN ZANDT: Many times, law enforcement and others who study these lone wolf type individuals, you have to make a decision: is this a lone wolf or is this a lone nut?

TEMPLE-RASTON: Experts say lone wolves generally fall into four categories: religious extremists, political terrorists, people who have long-standing mental problems and those who just snap. The man who allegedly shot a soldier at a recruiting center in Arkansas last month was a Muslim convert who was angry over deaths he witnessed in Afghanistan. Van Zandt says he would fall into the religious extremist category.

The Holocaust Museum suspect had been nursing a lifetime of racial resentments. That kind of person, according to the FBI's Van Zandt, is considered a political terrorist.

Mr. VAN ZANDT: There are going to be those who will say von Brunn just snapped. But if you go back, if you do a psychological autopsy of the shooter, you find that there were telltale indicators.

TEMPLE-RASTON: Indicators like racist essays von Brunn allegedly wrote and his clear mistrust of the government. But the FBI didn't see those warning signs because they didn't have von Brunn under surveillance. And that gets to the crux of the problem: it isn't illegal to be racist, so law enforcement can't move in, or in some cases even watch someone, until they have evidence that a crime might be committed.

Professor SAM RASCOFF (Law, New York University School of Law; Former Director of Intelligence Analysis, New York City Police Department): Let's not forget that the government is inevitably constrained by resources.

TEMPLE-RASTON: Sam Rascoff used to work intelligence issues at the New York Police Department and is now at New York University Law School.

Mr. RASCOFF: As a practical matter, it can't possibly play man-to-man defense against absolutely everyone who, some day, might translate some sort of hateful ideology into violent action.

TEMPLE-RASTON: Because of the inability to play man to man, late last year, the FBI launched Operation Vigilant Eagle. Rascoff says the idea is to reach out to White supremacists and militia groups and convince them to report outliers to the authorities.

Mr. RASCOFF: Sometimes the lone wolves are the dropouts from those groups. They're the individuals deemed by the leadership of those very groups to be too unreliable or, for that matter, too unstable to actually play in the big leagues. So, by keeping an eye on the traditional groups, you might also be doing important work in protecting against the lone wolf.

TEMPLE-RASTON: That said, in the three most recent killings, that strategy would have been of little use. Van Zandt says that's why trying to stop a lone wolf attack requires a combination of good luck and foresight.

Mr. VAN ZANDT: You know, with 310 million people, there are a lot of people that are on the fringe of society. What we have to be able to discern is who are the fringe of the fringe. Who are the ones so far out there that their ideation, their thought process, is actually moving toward action and then how do we intervene before they take that action?

TEMPLE-RASTON: And authorities have to find a way to do that without trampling on a suspect's rights. That's why one FBI agent said that when it comes to a lone wolf, the bureau's hands are tied. Until a suspect is about to move, there is little law enforcement can do. And often, by that time, it's too late.
