Police Practices

Police Practices

Good police practices, thorough training, carefully crafted policies and appropriate allocation of resources in law enforcement can ensure public safety and prevent abuses in encounters between police officers and citizens. Unfortunately, across the nation patterns of racial profiling, the selective enforcement of laws against people of color and disturbing stop-and-frisk policies have resulted in a disproportionate effect on certain communities, with people of color coming in contact with law enforcement and the criminal justice system at far greater rates that white people.

In addition to our work to promote fair and effective police practices, the ACLU has defended the rights of police officers, firefighters and corrections officers throughout the nation. For examples of the ACLU's legal advocacy on behalf of law enforcement officials, go here.

Racial profiling is a practice that offends fundamental principles of our Constitution. Racial profiling disproportionately targets people of color for investigation and enforcement, which alienates communities from law enforcement, hinders community policing efforts, and causes law enforcement to lose credibility and trust among the people they are sworn to protect and serve. We rely on the police to protect us from harm and expect them to promote fairness and justice in our communities. Racial profiling, however, has placed communities of color in fear and created a racially biased system of law enforcement that casts entire communities as suspect.

Civil Asset Forfeiture

Every year, federal and state law enforcement agents seize millions of dollars from civilians during traffic stops, simply by asserting that they believe the money is connected to some illegal activity and without ever pursuing criminal charges. Under federal law and the laws of most states, they are entitled to keep most (and sometimes all) of the money and property they seize.


The war on drugs has been a war on communities of color. Despite the fact that whites engage in drug offenses at a higher rate than African-Americans, African-Americans are incarcerated for drug offenses at a rate 10 times greater than whites. The selective policing and prosecution of low-level offenses in communities of color has led to huge racial disparities in our criminal justice system – from who is stopped, to who is charged with a crime, to who ends up under correctional control.

[Infographic] Combating Mass Incarceration - The Facts (2011 infographic)

An Infographic on Mass Incarceration: America's criminal justice system should keep communities safe, treat people fairly, and use fiscal resources wisely. But more Americans are deprived of their liberty than ever before - unfairly and unnecessarily, with no benefit to public safety. Especially in the face of economic crisis, our government should invest in humane and fiscally sound alternatives to incarceration that promote the long-term community health and safety and make prisons options of last – not first – resort.

Stun Gun Fallacy: How the Lack of Taser Regulation Endangers Lives


The Department of Justice's Civil Rights Division has the authority to investigate police departments to determine whether police officers and departments are abusing their authority, through excessive force, corruption or discrimination against minority populations. Under the Obama administration, DOJ is conducting the largest number of civil rights investigations of police departments in its history. The result of an investigation is the issuance of extensive recommendations by the DOJ about how to best reform the problems plaguing the department under investigation.

In several cities ACLU affiliates have led the push for DOJ investigations, taking the initiative to document the problem within the community and directly petitioning the DOJ to investigate their police departments. In multiple jurisdictions, DOJ launched investigations and issued findings as a direct result of the work of the ACLU.
