Why Tasers Failed in Times Square Attack: Body Composition's Role
One woman, age 32, was killed; one man, age 68, was wounded in the stabbing attack; the suspect was fatally shot by police.
Muscle conducts electricity much better than fat
Mark
So the Taser didn't work because of her weight?
Mimi
That's part of it, but not the whole story. Body fat interferes with the electrical connection between the two probes, but there were other factors too—her mental health history, the chaos of the moment, the clothing she was wearing.
Luke
How much do we actually know about her body composition? The reporting doesn't give us her weight or any medical details. We're inferring from the Taser failure that body fat was a factor, but that's one expert's explanation among several.
Mark
What are the other reasons Tasers fail?
Mimi
Probe placement is huge—if one probe hits and the other misses, the whole thing falls apart. Clothing can block contact. Substance use can make someone less responsive. Mental state matters too.
Luke
And we don't know which of those applied in this specific case. The reporting tells us Cisneros had a mental health history, but nothing about what she was wearing, whether she was under the influence, or exactly where the probes landed.
Mark
So why are we talking about body composition at all?
Mimi
Because it's a real factor in Taser effectiveness, and this incident raised the question. Muscle conducts electricity better than fat, so officers trained to aim for the back and thighs might miss those targets or hit fat layers instead.
Luke
True, but the reporting leans heavily on body composition as an explanation without confirming it was actually the problem here. It's plausible, it's worth discussing, but it's not proven in this case.
Mark
What should change?
Mimi
Departments might need to rethink training and tactics for people with different body types, and they need to account for mental health crises where the Taser might not work no matter what.
Luke
That's reasonable, but it's also speculative. The reporting doesn't tell us whether the NYPD is actually considering changes or whether this is just one incident that raised questions.
O Pulso
- A 49-year-old woman stabbed two strangers in Times Square, killing one, before advancing on officers with knives and a declaration that she would not surrender — setting off a desperate four-minute standoff.
- Multiple Taser deployments failed entirely, leaving officers with narrowing options as the suspect continued moving toward them undeterred by repeated electrical shocks.
- Experts point to a convergence of failure conditions: thick body fat disrupting electrical conductivity between probes, a documented mental health history that may have overridden the device's neuromuscular effects, and the chaos of a live confrontation undermining precise probe placement.
- The physics are unforgiving — a Taser requires two probes at least 12 inches apart making clean contact with conductive tissue, and any deviation, whether from clothing, body composition, or missed placement, can break the circuit entirely.
- Police ultimately opened fire, and the suspect was pronounced dead at Bellevue Hospital, forcing departments nationwide to confront whether training and deployment protocols have kept pace with the real-world diversity of the people officers encounter.
On a Monday afternoon in the heart of New York City, a four-minute confrontation ended in death for both a 32-year-old woman and the woman who stabbed her, exposing a quiet fault line in modern policing: the assumption that less-lethal tools will work when it matters most. The Times Square incident has drawn experts and officials into a long-overdue reckoning with the limits of Taser technology — limits shaped not by malfunction, but by the irreducible complexity of the human body and mind. What failed that afternoon was not simply a device, but a set of assumptions about who these devices were designed for.
On a Monday afternoon in Times Square, Pamela Cisneros, 49, stabbed two people — a 32-year-old woman who died and a 68-year-old man who was wounded — before officers arrived and attempted to subdue her. What followed was a roughly four-minute standoff in which multiple Taser deployments failed to stop her advance. Telling officers she would not drop her knives and would rather kill them, she kept moving. Two officers eventually opened fire. Cisneros was taken to Bellevue Hospital and pronounced dead.
The failure of the Tasers has reopened a question law enforcement has long struggled to answer cleanly. A standard Taser fires two barbed probes connected by wires that deliver electrical pulses, triggering involuntary muscle contractions — but only when both probes make contact at least 12 inches apart on conductive tissue. Retired police sergeant Steve Keller explained that a thick layer of body fat can break this circuit entirely: if one probe strikes fatty tissue and the other misses or hits clothing, the device simply will not discharge. Even when both probes connect through a fat layer, the shock may be felt without producing the muscular incapacitation the device is designed to cause.
Dr. Marc Siegel reinforced the underlying physiology — muscle conducts electricity far more efficiently than fat, and a Taser engineered around a certain body type loses reliability as that baseline shifts. But the Times Square case was not reducible to physics alone. Police Commissioner Jessica Tisch confirmed that Cisneros had a documented mental health history with the NYPD. Keller noted that acute psychological distress can override a Taser's effects independent of body composition — the device assumes a normally functioning nervous system, and a mental health crisis can shatter that assumption entirely.
Other compounding factors — heavy clothing, imprecise probe placement under pressure, and the cumulative chaos of a prolonged confrontation — stacked against the officers in real time. The incident has made it harder to ignore the growing gap between how Tasers perform in controlled training environments and how they perform on the street, against people whose bodies and mental states fall outside the parameters these devices were built around. Whether law enforcement agencies will revise their protocols in response remains an open question.
On a Monday afternoon in Times Square, officers confronted Pamela Cisneros, 49, after she had stabbed two people—a 32-year-old woman who died and a 68-year-old man who was wounded. What followed was a roughly four-minute standoff in which multiple officers deployed Tasers that failed to stop her. As she advanced toward them with knives in hand, telling officers "I'm not dropping anything. I would rather kill both of you," the devices proved useless. Eventually, two officers opened fire. Cisneros was taken to Bellevue Hospital and pronounced dead.
The incident has forced a reckoning with a question law enforcement has grappled with for years: why do Tasers sometimes fail? The answer, experts say, is more complicated than a simple mechanical malfunction. A standard Taser works by firing two small barbed probes connected by insulated wires that carry electrical pulses into the body, triggering involuntary muscle contractions. For this neuromuscular incapacitation to work, the two probes need to make contact at least 12 inches apart. Officers are trained to aim for large muscle masses—the back and thighs—where electrical conductivity is strongest.
But body composition can interfere with this basic calculus. Steve Keller, a retired police sergeant in Blue Ash, Ohio, explained that a thick layer of body fat can disrupt the electrical connection between the two probes. If one probe strikes the abdomen of someone with significant body fat, and the other misses or hits clothing, the circuit breaks. The Taser simply will not fire. The same problem occurs if one probe hits a heavy winter jacket while the other finds skin. "If one probe hits the person and the other probe misses, the Taser will not work," Keller said. Even when both probes make contact through a fat layer, the device may still function but with reduced effectiveness—the person might feel the shock but retain enough muscular control to keep moving.
Dr. Marc Siegel, a Fox News medical analyst, reinforced this point: muscle conducts electricity far more efficiently than fat. A Taser delivers high voltage, and that voltage travels readily through muscle tissue. In someone with obesity, finding an area with sufficient electrical conductivity becomes harder. The device was engineered for a certain body type, and deviations from that baseline reduce its reliability.
But the Times Square case involved more than just physics. Police Commissioner Jessica Tisch noted at a press conference that Cisneros had a documented mental health history with the NYPD—incidents recorded in 2018 and 2019. Keller emphasized that mental state plays a significant role in how someone responds to a Taser, independent of body composition. A person in acute psychological distress, experiencing delusions or extreme agitation, may simply override the device's effects through sheer force of will or neurochemical state. The Taser assumes a certain baseline of normal nervous system function; mental health crises can shatter that assumption.
Retired Sergeant Keller also pointed to other common causes of Taser failure: heavy clothing, poor probe placement under pressure, and substance use by the suspect. Each of these factors can operate independently or in combination. In Cisneros' case, multiple failures stacked on top of each other—body composition, mental health history, the chaos of a four-minute confrontation. The officers had limited options and made a lethal choice.
The incident has raised questions about whether law enforcement training and deployment protocols need revision. Officers are trained to adjust their aim based on clothing and distance, but the interaction between body composition and electrical conductivity remains poorly understood in the field. As departments across the country rely increasingly on Tasers as a less-lethal alternative, the gap between how these devices perform in controlled settings and how they perform on the street—against people of varying body types, mental states, and levels of agitation—has become impossible to ignore.
