Despite the important role law enforcement plays in maintaining safety and order, there are undeniable instances where officers violate the very laws they swear to uphold. These abuses not only erode public trust but also undermine the foundation of justice.
Although most police officers strive to serve ethically, some continue to engage in practices that are clearly illegal or unconstitutional. Here’s a look at some of the most troubling illegal acts that persist among US law enforcement, why they happen, and what it means for our communities.

1. Using Excessive Force Beyond Legal Limits
One of the most well-documented illegal behaviors among police officers is the use of excessive force. While officers are authorized to use necessary force to protect themselves or others, they cross the line when they apply more force than what is reasonable under the circumstances.
High-profile cases have revealed officers striking restrained suspects, using dangerous chokeholds, or employing tasers unnecessarily. These acts violate the Fourth Amendment, which protects people from unreasonable seizures, and numerous federal court rulings have reaffirmed that excessive force is illegal.
The tragic death of George Floyd in 2020 shone a harsh light on the unlawful use of force, specifically the use of prolonged neck restraints. Even though many departments officially ban chokeholds, some officers still use them, ignoring policies and federal guidelines. Excessive force not only inflicts physical harm but also leads to civil rights lawsuits costing taxpayers millions of dollars each year.
2. Conducting Illegal Searches Without Warrants or Probable Cause
The Fourth Amendment guarantees the right to privacy, requiring police to have a warrant or probable cause before searching private property. However, illegal searches remain a widespread issue.
Officers sometimes conduct searches without a warrant, hoping to find incriminating evidence, or they exploit vague consent obtained under duress. When police search vehicles or homes without a valid legal basis, they violate constitutional rights.
Many Americans are unaware they can refuse a search without a warrant, and some officers take advantage of this ignorance. The Supreme Court has ruled repeatedly that evidence obtained from illegal searches must be excluded from court, but even so, some officers gamble on illegal searches because many people don’t challenge them in court.
3. Fabricating or Planting Evidence
While not common across the board, cases of officers planting drugs, weapons, or other incriminating materials have been exposed in multiple states. These actions are among the most dangerous violations of the law, undermining the integrity of the justice system.
Fabricating evidence can ruin innocent lives, send people to prison for crimes they didn’t commit, and deepen mistrust between communities and law enforcement.
In Baltimore, the Gun Trace Task Force scandal revealed officers planting fake evidence on innocent people to secure arrests or inflate crime statistics. Officers involved faced federal charges, but the damage to public confidence lingered long after their convictions.
4. Coercing Confessions Through Illegal Tactics
Police are allowed to interrogate suspects, but the law prohibits coercion or abusive tactics to extract confessions. Yet reports of officers threatening suspects with violence, lying about evidence, depriving them of food or sleep, or psychologically manipulating them beyond what is legally permissible continue to surface.
Such illegal coercion violates the Fifth Amendment right against self-incrimination and the Fourteenth Amendment’s due process protections.
Wrongful conviction cases have repeatedly revealed coerced confessions, sometimes involving juveniles or mentally impaired individuals who were unable to withstand aggressive interrogation. Organizations like the Innocence Project have documented how these Illegal confessions contribute significantly to false convictions.
5. Engaging in Racial Profiling
Racial profiling, or targeting individuals for suspicion of crime based solely on race or ethnicity, is not just unethical. It is illegal under federal civil rights laws. Despite that, it persists in many police departments. Studies show that minorities are disproportionately stopped, searched, and arrested compared to white individuals, even though crime rates don’t justify the disparity.
Federal courts have ruled that racial profiling violates the Equal Protection Clause of the Fourteenth Amendment, yet data from traffic stops and pedestrian stops in major cities reveal continued patterns of discrimination. Such practices not only break the law but also cause tensions between law enforcement and marginalized communities.
6. Falsifying Police Reports
Honest, accurate police reports are fundamental to fair trials and justice. But some officers falsify reports by misrepresenting facts, omitting key details, or outright lying about events. This can happen when an officer tries to cover up misconduct, justify illegal arrests, or secure convictions. Perjury in police reports is a crime, yet it still happens.
Falsified reports can lead to wrongful arrests, unjust convictions, and massive legal settlements. High-profile cases have exposed officers inventing entire narratives to protect themselves or colleagues, a practice sometimes referred to as the “blue wall of silence.”
7. Performing Retaliatory Arrest Against Critics
The First Amendment protects the right to free speech, including criticizing the police. However, some officers retaliate against people who film them, speak out against them, or question their authority by arresting them on trumped-up charges like disorderly conduct or obstruction. These retaliatory arrests are illegal, violating constitutional protections of free expression.
Courts have repeatedly ruled that officers can’t arrest citizens for exercising their right to record police activity in public. Nonetheless, videos of people being arrested for filming officers have always circulated online, showing this illegal practice continues despite clear legal precedent.
8. Misusing Civil Asset Forfeiture
Civil asset forfeiture allows police to seize property they suspect is connected to criminal activity, but some officers abuse this power by confiscating cash, cars, or other valuables without actually charging the owner with a crime.
Although recent reforms in some states have tightened forfeiture laws, loopholes still enable officers to seize property with little oversight.
This practice violates the principle of due process under the Fifth and Fourteenth Amendments when it’s used punitively rather than to fight crime. For years, critics have documented cases of innocent people losing significant property with little chance to recover it, raising concerns about “policing for profit.”
9. Tampering with or Destroying Evidence
Destroying, concealing, or altering evidence is illegal under both state and federal laws, yet some officers have done so to protect themselves or colleagues from accountability. Body camera footage has occasionally gone missing under suspicious circumstances, or key evidence in police misconduct cases has been destroyed.
Tampering with evidence not only obstructs justice but also violates multiple criminal statutes.
Such actions can have devastating consequences for victims seeking justice, as the loss of critical evidence can mean wrongful acquittals or inability to prove misconduct.

10. Violating Miranda Rights
Since the 1966 Miranda v. Arizona ruling, police are required to inform suspects of their rights to remain silent and to an attorney before custodial interrogation.
Despite this, some officers intentionally skip or rush through Miranda warnings or continue questioning suspects after they invoke their rights. These violations render any obtained statements inadmissible in court, but many defendants don’t realize this or lack resources to fight it.
Failure to properly administer Miranda rights is a serious breach of constitutional protections and can lead to wrongful convictions if unchallenged.
11. Conducting Illegal Surveillance Without Warrants
With the rise of technology, some police departments have engaged in electronic surveillance without proper judicial authorization. Using devices like StingRays to track cell phones, or conducting GPS tracking without warrants, are violations of the Fourth Amendment’s privacy protections.
While the Supreme Court has established clear requirements for digital surveillance, reports continue to surface of law enforcement agencies sidestepping these legal obligations.
Illegal surveillance not only affects criminal suspects but also journalists, activists, and ordinary citizens who find their movements tracked without cause.
