Story highlights

Police used a robot to deliver an explosive that killed shooter in Dallas
P.W. Singer: While it's a first, it doesn't necessarily mean the beginning of routine use of robots in this way

(CNN)The use of a robot to kill the man who authorities say fatally shot five Dallas police officers has drawn attention in part because it's the first time police have used robots in such a manner.

Below is a series of questions that I have been asked frequently and preliminary answers. The facts remain incomplete, so these are preliminary thoughts.

What happened?

In the wake of the shooting of the Dallas police officers Thursday night during a peaceful protest, police cornered the shooter -- Micah Xavier Johnson -- in a parking garage. After an hours-long standoff that included exchanges of gunfire, they used a robot to deliver an explosive that killed the gunman.

Why did they use it?

Peter W. Singer

"We saw no other option but to use our bomb robot and place a device on its extension for it to detonate where the subject was," Dallas Police Chief David Brown said at a news conference Friday morning. "Other options would have exposed our officers to grave danger."

What robot was used?

The system has been reported as a Northrop Grumman Remotec Andros, which is a remotely-controlled bomb disposal robot commonly used by police, military and other first responders around the world. It is wheeled, weighs around 220 kg (485 pounds), and mounts various sensors and a robotic arm with grippers.

Why is this being reported as a big deal?

This is the first use of a robotic system by the police in a deliberately lethal manner.

Dallas: An act of domestic terrorism

Are there parallels or past precedents by the police?

Robots are used all the time by police bomb squads forces around the world in bomb disposals. They are also frequently used in surveillance roles by SWAT teams and the like. They have been used in standoffs with armed gunmen in a variety of examples, from helping to figure out where the gunman is hiding to delivering pizza to the gunman and hostages during negotiations when a person wasn't allowed in. But none of these involved delivering lethal force.

The closest parallel I am aware of was a case in 2011, when police in Tennessee strapped tear gas grenades to a robot that then accidentally started a fire in a mobile home. This doesn't seem a great parallel, as it does not reflect a decision deliberately to use the robot to kill. Another parallel would be the 1985 standoff in Philadelphia between law enforcement and the MOVE group. Manned police helicopters dropped two small explosive devices on the roof to try to open a breach into the building below where the group was bunkered in. Instead, the building caught fire, killing 11 in the blaze, and burning down many neighboring buildings. Again here, the parallel isn't a perfect one. While it did involve a bomb, there was no robot, nor was it a deliberate use in the way authorities used the robot in Dallas.

In a violent, angry America, a plea for peace

What about in war?

The best parallel that I am aware of is a case that I wrote about in my 2009 book "Wired for War." A U.S. Army soldier discussed how his unit in Iraq in the mid 2000s was equipped with a surveillance robot known as a MARCBOT. This is a remotely operated surveillance robot, equipped with a mast holding a small camera, not the kind used in Dallas. It costs about $8,000. Their unit used the robotic system for roles like checkpoint duty; if there was a car that was suspected of being a car bomb, they would send the robot for a close look, rather than a risk one of their people.

When they faced off with an armed insurgent holed up in an alley, the soldier told of how they came up with an ad hoc answer. They jury-rigged the robot with an explosive device (literally duct-taping a claymore mine on it) and drove it down the alley to kill the insurgent, rather than risking a soldier.

After Dallas, tone it down

Why would the police have a bomb with them?

It has not been reported which type of explosive was used, but it is important to note that it was clearly not the common image of a "bomb" like the type dropped by an F-16. Police SWAT teams have small explosive charges that they use for breaches (to blow open a locked door or a hole in the wall to get around a gunman behind a door), while bomb squads sometimes will place small explosive charges beside a known or suspected bomb to detonate it in a safe manner.

How does this link to the "killer robots" debate?

While there are links to the discussion on the future of killer robots, known as LAWS (lethal autonomous weapons systems), there are also three important differences to keep in mind. First, this was not an autonomous robot; both the robot and the explosive were remotely operated. Second, this was not a designed weapons system. There are many ground robots under development that are armed with weapons like machine guns and missile launchers, from the prototypes of the US MAARS to the Chinese Sharp Claw. But this was the case of using an older robot designed for something else. And, third, the concerns driving the "killer robots" debate center on whether we can prevent the unleashing of self-operating robots on the battlefield, for which militaries around the world are beginning to establish plans and doctrines. The debate is driven by a concern that such a future might cause both greater civilian harm and a lack of accountability.

By contrast, this was an ad hoc use, just like the case in Iraq. There is no doctrine that planned this out, no training manuals that police were following, nor development programs for this use. It also doesn't appear to have risked civilian harm or raised accountability concerns of the kind that motivate the killer robots debate. There are links to that debate but they are more about the many different directions robot use might go to next.

But doesn't it portend a future of lethal police robots?

It is too early to draw that conclusion. An important first use of robots in a lethal way by police was established. But you can counter whether that important first will open the floodgates with two opposite points. First, police forces around the world are already equipped with this type of robotic system. So it can't cause mass spread of the technology since that spread was already under way. And, second, important precedents of use aren't always followed. They can either prove to be exceptional circumstances or the public and/or police decide against them in the aftermath. Take the case of the 1985 MOVE standoff; police helicopters dropped bombs, but that didn't become a common practice in the years since.

What we can confidently conclude is that we will see greater and greater use of robotics in all sorts of roles, whether it be by the military, law enforcement, or just the rest of us in civilian life. Indeed, some 80 plus countries already have robotics in their militaries, while companies that range from Google to Tesla to Uber to Ford are planning on a future of "driver-less cars." In policing, the robotics trend has been moving towards greater use of drones in surveillance roles, from smaller ones that might be used by individual units to large ones that could monitor an entire neighborhood or city.

The key here is to distinguish the decision of unmanning a system from arming it. Just as manned police planes or helicopters are not armed (police don't fly Apache attack helicopters or F-16s), the trend towards their unmanning doesn't somehow mean they have to be armed. So, too, manned police ground vehicles, whether they be patrol cars or even military surplus MRAPS don't mount cannons or machine guns like their military equivalent; neither do the unmanned versions have to be armed by definition.

Before this incident, when it came to arming robotic systems in a law enforcement role, most of the discussion has been of ones using "less than lethal" weapons. At a number of trade shows, robotic systems have been displayed that mount tasers and tear gas to China's controversial Anbot, which is a police bot designed to operate autonomously and equipped with an electroshock device similar to a cattle prod. These, of course, prompt great debate that brings together elements of the robotics argument with the question over whether "less than lethal" weapons actually lead to abuse (think about the debate over Tasers; they arguably save lives, yet might be used more often).

How to talk to your kids about violence (Opinion)

Did the Dallas Police do the right thing?

I'm not going to second guess them. The information isn't all in, emotions are high, and the best judges of that are going to be experts on SWAT team tactics and lawyers that specialize in police use of force issues. In no way, shape, or form is any of this a condemnation. Indeed, it is the opposite. My reaction is similar to the one I had to the case mentioned above in Iraq; I wasn't there, but can certainly understand and, even more, empathize with what the people on the scene decided to do. At the same time, my analytic side can recognize that this is a big issue that has provoked debate.

Is this another sign of the "militarization" of police in the U.S.?

I have a hard time making that connection now. The debate over the militarization of the police seems to turn on 1) the use of equipment designed for war, often provided in surplus from the U.S. military, and 2) in a manner that is intimidating or threatening to the public.

In this incident, the technology is not one that is only used in war and it was not used in a way that was targeting the broader public; indeed it was the opposite. Remember, the police in Dallas who were shot and killed were there protecting peaceful protesters, not intimidating them. Images from the scene beforehand showed police and protesters smiling together. In turn, when violence struck, the police on the scene bravely moved protesters to safety, while the media reported that protesters helped police find the shooter. The police and protesters were in it together; so we, in turn, should not let people try to exploit the tragedy as a means to divide.
