Why This Case Still Matters — 47 Years Later
Popow v. City of Margate was decided in 1979. It's not a Supreme Court case. It's a federal district court opinion from New Jersey. And it is still cited in firearms training liability cases today, nearly half a century later, because it said something that no court had said so clearly before: if your officers' firearms training consists only of standing still on a range and shooting at a stationary paper target, that training is grossly inadequate for the job they actually do.
This case is the reason your agency is expected to include low-light training, moving targets, and realistic scenario elements in its firearms program. It's the case that drew the line between marksmanship and preparedness. And it's the case that tells training officers: your qualification course must reflect the environment your officers actually work in — not the controlled conditions of a flat range on a clear afternoon.
What Happened
Margate, New Jersey is a small, almost entirely residential coastal city. On the night in question, two Margate police officers were pursuing a man they believed to be a fleeing kidnapping suspect through a residential neighborhood. Officer George Biagi fired shots at the suspect as he ran down the street.
Darwin Popow was not the suspect. He was an innocent bystander who had stepped onto his front porch to see what the commotion was about. One of Officer Biagi's rounds struck and killed him.
Rosemary Popow, Darwin's widow, filed a civil rights lawsuit under 42 U.S.C. § 1983 against both Officer Biagi and the City of Margate. The case centered on two questions: whether Biagi's conduct was grossly negligent, and whether the City of Margate's training and supervision of its officers was so inadequate that it amounted to a de facto policy of acquiescing to constitutional violations.
What the Court Found About Training
The court examined the Margate Police Department's firearms training program in detail. What it found became the benchmark for what courts consider inadequate. During his deposition, Officer Biagi testified that he had received training on the use of deadly force at the state police academy — ten years before the shooting. His only continuing firearms training since then consisted of going to a range approximately every six months.
The court identified five specific deficiencies in Margate's training program, and each one has become a standard reference point in subsequent litigation.
1. No training on moving targets.
Officers were trained to shoot at stationary paper silhouettes. They never practiced engaging a target that was moving — despite the obvious reality that suspects flee, bystanders move, and the officer's own position shifts during a foot pursuit. The court noted that this disconnect between training and reality was a fundamental inadequacy.
2. No training on low-light or night shooting.
All training occurred during daylight hours at a standard outdoor range. Officers received no instruction on firing under low-light or nighttime conditions — despite the fact that a significant percentage of police encounters occur at night. The shooting that killed Darwin Popow happened at night.
3. No training on shooting in residential areas.
Margate is almost entirely residential. The court found it was not even "remotely" unlikely that a Margate officer would have to chase a suspect through a residential neighborhood. Yet the training program provided no instruction on the considerations unique to discharging a firearm in a residential environment — backdrop awareness, bystander risk, penetration concerns.
4. No practical application of laws and policies.
Officers had access to written regulations on the use of deadly force, but the court found that they "viewed no films or participated in any simulations designed to teach them how the state law, city regulations or policies on shooting applied in practice." In other words, the agency had a use-of-force policy on paper but never trained officers on how to apply it in the real world.
5. No meaningful discipline for prior incidents.
Officer Biagi had been involved in two prior shooting incidents — in 1972 and 1974. The chief of police acknowledged that Biagi's conduct in the earlier incident was wrongful. Yet Biagi was never disciplined for any of them. The court found this created an issue of fact as to whether the city's practices were "so grossly inadequate as to give police officers the idea that their unconstitutional conduct would have no substantial adverse consequences for them."
The court's central finding was devastating in its simplicity: "The possibility that a Margate police officer will in the course of his duties have to chase a suspect in a residential area at night is not in the least remote." Yet the training program addressed none of those conditions. That gap between the training provided and the duties performed is what the court called "grossly inadequate."
The Legal Standard Popow Established
Popow was decided ten years before City of Canton v. Harris formalized the "deliberate indifference" standard at the Supreme Court level. But the reasoning in Popow anticipated Canton and has been cited alongside it in hundreds of subsequent cases. The Popow court applied the standard from an earlier case, Leite v. City of Providence, which held that a municipality can be liable when its training is "so reckless or grossly negligent as to make future police misconduct almost inevitable."
The practical standard Popow established, which courts still apply, is this: firearms training must be regular and realistic. "Regular" means ongoing, not a one-time academy course followed by infrequent range visits. "Realistic" means it must reflect the actual conditions officers will encounter — low light, movement, residential environments, time pressure, and decision-making under stress.
Subsequent courts have built on Popow to require what the profession now calls the core elements of realistic firearms training: moving targets, low-light or adverse-light conditions, residential or urban environment considerations, mandatory in-service training on a continuing basis, and — following Zuchel v. Denver — shoot/don't-shoot judgment training.
The Documentation Lesson Hidden in Popow
The training deficiencies in Popow were established primarily through deposition testimony. Officer Biagi described his own training under oath. The chief of police described the department's training program. And the court drew its conclusions from what that testimony revealed.
Here's the uncomfortable implication: if the Margate Police Department had been documenting its training more carefully, one of two things would have been true. Either the documentation would have revealed the same gaps the depositions revealed — making the case even easier for the plaintiff. Or the documentation would have shown that the training was better than what came out in testimony — which would have been a defense.
Either way, the absence of detailed training records left the agency without evidence. When Biagi testified that he'd received his deadly force training at the academy ten years prior and his only continuing training was range time twice a year, there was no training record to contradict that testimony or add context to it. The testimony was the record.
This is why training documentation standards matter as much as the training itself. Your documentation either confirms or contradicts what witnesses say in depositions. If your records are complete, they tell the story you want told. If they're incomplete or absent, the story gets told by whoever is being deposed — and you can't control that narrative.
What This Means for Your Agency
If your firearms qualification program consists only of a static, daytime, marksmanship course on a flat range, Popow says your program is vulnerable. The court made clear nearly five decades ago that training must match the conditions officers will face. If your officers work nights, your training must include low-light components. If they work in residential areas, your training must address bystander risk. If suspects move, your training must include moving targets. And all of it must be documented.
Here's a practical self-assessment based on the five deficiencies the Popow court identified:
Do your officers train on moving targets? Not every range can accommodate robotic movers or turning targets. But even simple lateral movement drills, shoot-while-moving exercises, or force-on-force scenarios address the Popow requirement. If every round your officers fire in training is at a stationary silhouette, you have a gap.
Do your officers qualify or train under low-light conditions? At least one qualification or training event per year should occur under reduced-light conditions. Document the lighting conditions, whether weapon-mounted lights were used, and the course of fire modifications. Some states, like New Mexico, specifically require day and night firearms training as part of their biennial in-service mandate.
Does your training address the environment your officers work in? Urban agencies need to address backdrop considerations and bystander awareness. Agencies with rural jurisdictions need to address engagement distances and terrain. The point is that your training should look like your jurisdiction, not like a generic flat range.
Do your officers receive practical instruction on applying deadly force policy? Having a written policy isn't enough. Popow found that the policy existed but officers never trained on how to apply it. Judgment-based training — simulators, tabletop exercises, scenario discussions, force-on-force with marking rounds — bridges the gap between policy and practice.
Does your agency hold officers accountable for prior incidents? Popow found that the city's failure to discipline an officer with multiple prior shooting incidents contributed to a culture of impunity. Your training program doesn't exist in isolation — it exists within a system of accountability that includes documentation, review, and when necessary, corrective action.
