OFF THE WIRE
Introduction
High speed police pursuits constitute one of the most dangerous 
aspects of police work.  Police shootings garner more attention, but 
many people are killed or severely injured as a result of fleeing 
suspects and pursuing police officers.  Hollywood movies typically 
depict police officers in “hot pursuit” of a dangerous criminal, but 
virtually never depict wholly innocent people, such as child passengers 
in the suspect’s vehicle, or pedestrian bystanders, being killed in 
crashes and yet they are among the casualties of high speed chases.  
Pursuit policies vary among police departments and in different 
geographical jurisdictions depending upon whether a city, county, or 
state legislature has chosen to address police pursuits.  This primer 
will provide an overview of this controversial subject and will 
recommend that police commanders and policymakers impose restrictions on
 police pursuits in order to enhance public safety.
The Controversy
When a police officer activates his vehicle’s siren and emergency 
lights, drivers are legally obligated to yield to that show of authority
 and to pull their vehicles over to the side of the road to await 
further instructions from the officer.  It is illegal for a driver to 
disregard the siren or emergency lights—especially in an attempt to 
elude the police.  In the vast majority of cases, drivers comply with 
the law and pull over to the side of the road.  However, there are 
thousands and thousands of cases every year where drivers break the law 
and try to speed away and elude the police.  When those situations 
arise, the police face a dilemma.  On the one hand, they are expected to
 apprehend lawbreakers and keep the community safe.  If they don’t 
pursue the violator, he might never be caught and he might also harm 
others as he accelerates in his bid to get away.  On the other hand, the
 pursuit itself creates a danger by having another vehicle, the police 
cruiser, attempting to match the now reckless speed of the suspect 
vehicle.
When people get killed or injured in crashes from police pursuits, a 
heated debate typically ensues over the cause of the accident.  Was it 
the suspect’s failure to pull over, or was it the police officer’s 
decision to pursue the suspect at high speeds?  Here are a few chases 
that ended with tragic results:
- In June 2016, Officer Stacey Baumgartner was in pursuit of a man who
 had allegedly urinated in public, and then drove away.  As 
Baumgartner’s cruiser sped into an intersection, she was hit by an SUV 
carrying a family of seven.  Both Baumgartner and an 11-year-old boy in 
the SUV died in the crash.
- In May 2013, police received a call about several women who had 
stolen some merchandise from Macy’s and departed in a waiting car.  
Several police cars chased the women’s vehicle at speeds exceeding 100 
mph.  The women eventually sped down a freeway exit ramp, ran a red 
light, and then crashed into Rosabla Quezada, who was driving her three 
sons home from school.  Quezada was killed and her 5-year-old son, Jose,
 was left with brain damage.
- In June 2013, high school senior Patrick Conway was out riding his 
Honda motorcycle.  A state trooper pulled him over because he did not 
have a license plate.  As the trooper stepped out of his cruiser, Conway
 sped off.  A few minutes later, after weaving through traffic at high 
speeds, Conway collided with a BMW and was killed.
- In July 2012, a convenience store manager called the police at 4 
a.m. to report that some teenage girls had just shoplifted some 
merchandise and had driven away.  When a police officer spotted the 
suspect vehicle, he gave chase.  A few minutes later, the carload of 
young girls crashed into a utility pole.  One of the passengers, 
12-year-old Casey Grace, was sent to Cincinnati Children’s Hospital 
Medical Center, where she was listed in critical condition.
- In September 2012, Officer Mark Taulbee heard a radio dispatch at 
2:30 a.m. that a man had taken a woman’s car after a domestic 
disturbance.  When Taulbee saw the Nissan Altima, he started to pursue 
it.  Shortly thereafter, Taulbee was killed after he lost control of his
 car and it flipped over into a ditch on the side of the roadway.
It is true that the suspect-driver is always partially responsible 
(and sometimes fully responsible) for any property damage or crash 
casualties because, as Supreme Court Justice Antonin Scalia once 
observed, it takes at least two drivers to have a chase. 
And yet it is not uncommon to find police officials trying to shift 
all responsibility for any harmful consequences on to the suspect-driver
 with the argument that had the suspect simply pulled over, as he is 
legally obligated to do, there would not have been any crash casualties.
  That sweeping claim is misleading and self-serving.  If an elderly 
lady obstinately refuses a police command to step out of her parked 
vehicle, the officer would not be justified in hitting her over the head
 with a baton.  Similarly, if a shoplifter keeps running after an 
officer shouts “Halt!” the officer would not be justified in shooting 
him in the back.  Disobedience to governmental authority cannot excuse 
brutality.  By the same reasoning, police pursuits can and should be 
evaluated separately from the suspect’s wrongful actions.
Best Practices
Federal appellate Judge Frank Easterbrook has suggested a 
cost-benefit analysis of high-speed chases.  According to Easterbrook, 
such an analysis would “consider not only the risks to passengers, 
pedestrians, and other drivers that high-speed chases engender, but also
 the fact that if police are forbidden to pursue, then many more 
suspects will flee—and successful flights not only reduce the number of 
crimes solved but also create their own risks for passengers and 
bystanders.”  A rigorous academic analysis is beyond the scope of this 
primer, but it will be useful to briefly address several preconceptions 
that would be pertinent to such an analysis, and also to consider the 
experience of certain jurisdictions that have embraced pursuit 
restrictions. 
The first preconception is that if high-speed pursuits are 
restricted, “everyone will just go ahead and flee the police.”  This is 
an exaggeration.  As noted above, in the vast majority of cases, drivers
 yield to the police siren and quickly pull over.  To do otherwise is to
 commit a new offense, something the vast majority of people will 
refrain from doing.  Limiting pursuits may bring about some increase in 
flight cases, but that would likely be on the margin and has to be 
weighed against the crashes and injuries averted because of the pursuit 
restrictions.
A second preconception is that high speed pursuits typically involve 
dangerous criminals.  The thinking here is that restricting pursuits 
cannot possibly make the community safer because with more violent 
offenders avoiding arrest, they will be free to create more mayhem in 
the community.  This preconception is perhaps understandable because it 
is a very common scenario in the movies and on television for the police
 to be chasing a dangerous villain at high speeds. Yet, experience shows
 that most pursuits are triggered by minor infractions.  According to 
USA Today, 90 percent of the police chases in California between 2002 
and 2014 were for vehicle code violations, not violent crimes. 
A third preconception is the idea that restrictions on police 
pursuits are tantamount to complete non-enforcement of law.  On this 
view, restrictions on police pursuits will make the community less safe 
because the scofflaws will be emboldened to commit even more 
infractions—even if they’re not violent offenses.  It is a mistake, 
however, to make the leap from certain pursuit restrictions to 
non-enforcement.  To take one example, some police departments will have
 police cruisers back off a chase on the ground but have a helicopter 
track the suspect vehicle from above.  When the suspect exits the 
vehicle, patrol officers are alerted and they will then move in to make 
an arrest.  
As noted above, pursuit policies vary among America’s 18,000 police 
departments.  In general, policies and practices have tightened somewhat
 over the past 20 years.  Whether because of increased media scrutiny, 
litigation fears, local politics, or conscientiousness, more and more 
departments are embracing pursuit restrictions.  Here are several best 
practices:
- Some departments restrict the types of crimes that can trigger a 
chase. For example, allowing police to chase a suspect who committed a 
violent felony, but not allowing pursuits for traffic violations. 
- Some restrictive policies focus on road conditions, including weather and traffic. 
- Some departments prohibit certain tactics used by officers during a 
pursuit in order to minimize the risk of an accident, such as ramming 
techniques.
- Most importantly, many jurisdictions require officers to get 
supervisor permission in order to initiate a pursuit. The purpose of 
this requirement is to take the decision out of the hands of the officer
 in the field, who is likely experiencing an adrenaline rush and tunnel 
vision. 
To identify best practices is not to say that they are common.  It is
 unfortunate that many police departments either continue to leave the 
pursuit decision to the discretion of officers in the field, or do not 
seriously discipline officers who disregard departmental policy.  Policy
 changes are too often ad hoc, after a tragedy, rather than after 
thoughtful consideration of the latest research. 
There is empirical evidence, for example, showing that suspects are 
likely to slow down to a safe driving speed if pursuits are called off. 
 University of South Carolina Professor Geoffrey Alpert  interviewed 
suspects after they were apprehended and found that 70 percent of 
suspects said they would have stopped their flight when they “felt 
safe.”  They classified “safe” as being 2 miles or 2 city blocks ahead 
of police. 
In 2010, the Milwaukee Police Department put in a place a more 
restrictive policy after pursuits caused the deaths of four innocent 
people in a short period of time. After the first tragedy, Police Chief 
Ed Flynn defended his department by telling everyone that the chase 
officers “followed department policy.”  After the second tragedy, Chief 
Flynn came to recognize that another policy would make his community 
safer.  Chief Flynn acknowledged that his immediate duty is “to protect 
life: the lives of the innocent, the lives of police officers and the 
lives of offenders.”
In 2006, the Dallas Police Department (DPD) put in place one of the 
most restrictive pursuit policies in the country. In 2011, while 
slightly altering the pursuit guidelines, the Dallas Chief of Police 
David Brown noted, “injuries and deaths to both officers and citizens 
have plummeted since the institution of the current policy. This must 
continue to be our focus when deciding to engage in high-risk activities
 such as police pursuits.” DPD restricts pursuits to situations where 
the suspect “poses a danger to the public that outweighs the risks posed
 by the pursuit” – e.g. violent felonies. 
One important way to avoid tragedies is to find alternatives to high 
speed chases.  “Bait vehicle” technologies have provided law enforcement
 with a powerful tool to catch car thieves in a safe and effective 
manner.  With the ability to shut down the engine of the bait car 
remotely, there is no need for a high-speed pursuit. Another alternative
 tactic, as mentioned above, is helicopters. While helicopters are 
expensive and not all police departments can afford them, it would be 
worthwhile to improve regional and interagency cooperation in order to 
avoid, or at least reduce, high-speed pursuits. Drones will doubtless be
 tested for pursuit surveillance as a less expensive substitute for 
helicopters over the next ten years.
A serious obstacle that has hobbled a thorough cost-benefit analysis 
of police pursuits has been inadequate information.  The National 
Highway Traffic Safety Administration (NHTSA) tries to track the 
circumstances of all automobile fatalities.  According to NHTSA, 
pursuits kill about 350 people every year.  However, NHTSA’s tally has 
severe limitations.  First, NHTSA only tallies deaths, not injuries.  
Second, even NHTSA’s fatality numbers are very likely to undercount the 
actual figure.  This is because NHTSA relies upon police department 
reports on the automobile deaths.  If the fleeing suspect hits a tree 
and dies, officers might report the fatality, but omit the circumstances
 of the police pursuit. 
USA Today discovered and reported on such discrepancies in NHTSA’s statistics.
In 2014, Texas created a public statewide database for 
officer-involved shootings.  Every police agency must report shootings 
to the state attorney general.  The attorney general (AG), in turn, is 
required to post information about the shooting within five days.  Each 
year, the AG must issue a public report summarizing his annual findings.
  Unlike some questionable proposals for federal data-collection,  this 
state-level data-gathering model is fully consistent with the 
constitutional principle of federalism.  Every state should have such a 
system in place, not just for shootings, but for police chases as well, 
whether there are casualties or not.  One of the benefits of 
decentralized policing is that departments can experiment with different
 policies, the results can then be studied, and best practices 
identified or refined.  To make the reporting model work, however, state
 policymakers must find a way to sanction local departments that do not 
meet their reporting responsibilities.
Conclusion
- High speed police pursuits are inherently dangerous.  They too often
 end in crashes that kill and severely injure people, including innocent
 bystanders.
- Many police pursuits are in response to non-violent offenses or even
 minor infractions.  The risks posed by high speed pursuits in such 
situations are unjustified.
- The legal standards that apply to police pursuits vary across 
jurisdictions, but it is possible to embrace best practices that go 
beyond the legal minimum standard.
- Although there are about 100,000 police pursuits and hundreds of 
casualties every year, policymakers have largely neglected this 
dangerous aspect of police work. State-wide policies should be in place 
to both restrict and track police pursuits.
