City Cops And Federal Law: Who Enforces What?

Whether a city cop can enforce federal law is a complex question. While local law enforcement officers are not typically authorized to enforce federal law, there are certain circumstances where they may be able to do so. For example, in the case of immigration law, federal law explicitly authorizes state and local police officers to enforce certain provisions. Additionally, local police officers can make arrests for federal crimes if state law permits them to do so and if federal law does not preclude them from taking action. However, it's important to note that local police officers cannot supersede federal law enforcement personnel and can be arrested for impeding a federal investigation.

Local law enforcement officials are not authorised to enforce federal law

Local police officers cannot enforce federal laws unless they have been specifically deputised by the federal government to do so. This typically occurs in three circumstances: when there is a written agreement between the U.S. attorney general and a state or municipality, in which local officers are deputised as immigration officers under federal supervision; when the U.S. attorney general declares an emergency due to an influx of aliens; or when enforcing specific criminal provisions of the Immigration and Nationality Act (INA).

In the case of Gonzales v. City of Peoria, it was held that local police are not precluded from enforcing federal statutes as long as state enforcement activities do not impair federal regulatory interests. However, local police cannot arrest for unlawful presence in the US without special federal authorisation. They can, however, arrest for lawful entry under the same conditions that apply to state law arrests.

While local law enforcement officials cannot directly enforce federal law, they can still assist federal agencies in their investigations. If local officers impede a federal investigation or prevent the lawful arrest of state citizens by federal agents, they can be arrested themselves.

Local police can't enforce immigration law

Local police officers are not generally authorised to enforce federal law. However, there are some exceptions to this rule, and the enforcement of immigration laws by local police has been a subject of debate.

In the US, the federal government has exclusive power over immigration law. The power to regulate immigration is vested in the federal government, which has enacted and extensively amended the Immigration and Nationality Act (INA). The INA establishes a set of rules for legal immigration and naturalisation, providing a system for processing and deporting illegal immigrants and specifying civil and criminal penalties for violations.

While the federal government has the ultimate authority over immigration law, there have been instances where local law enforcement has been involved in immigration enforcement. For example, the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 added Section 287(g) to the INA, authorising US Immigration and Customs Enforcement (ICE) to delegate immigration officer functions to state and local law enforcement officers under their direction and oversight. This allows for collaboration between ICE and local law enforcement to identify and remove criminal aliens amenable to removal from the US. Additionally, in 2001, the INS began sending the names of thousands of noncitizens to the NCIC databases, and Attorney General Ashcroft confirmed that local officials have the "inherent authority" to enforce federal immigration law.

However, it is important to note that the involvement of local law enforcement in immigration enforcement has been controversial. Some communities have taken steps to limit the involvement of local authorities in immigration law implementation, citing concerns over proper training, finite resources, possible civil rights violations, and the impact on communities. Furthermore, while local police may have the authority to enforce certain criminal provisions of the INA, civil immigration law enforcement has generally been viewed as a federal responsibility.

In conclusion, while there may be exceptions and instances of collaboration, local police generally cannot enforce immigration law, as it falls under the exclusive jurisdiction of the federal government.

State and local police can arrest people for violations of federal criminal law

While there is no federal police force per se, federal laws take precedence over state laws. Local law enforcement officials are generally not authorised to enforce federal law. However, there are exceptions to this rule. For example, in the case of Gonzales v. City of Peoria, the Ninth Circuit Court of Appeals ruled that federal law does not prevent local enforcement of the criminal provisions of the Immigration and Nationality Act (INA). This means that state and local police officers can arrest people for violations of federal criminal law, but only if federal law explicitly or implicitly allows them to make an arrest for that specific crime.

In Connecticut, for instance, state and local police are authorised to arrest people for violations of federal criminal law. However, this is dependent on federal law permitting such an arrest. Similarly, federal immigration law authorises state and local police to enforce its provisions under three circumstances. Firstly, a written agreement between the U.S. attorney general and a state or municipality, in which state or local officers are deputised as immigration officers under federal supervision. Secondly, the U.S. attorney general can declare an emergency due to an influx of aliens. Thirdly, the enforcement of a specific criminal provision of the INA.

In addition, local police officers may, subject to state law, constitutionally stop or detain people when there is reasonable suspicion or probable cause that they have violated, or are violating, the criminal provisions of the INA. This was demonstrated in the case of People v. Barajas, where the California Court of Appeal upheld the authority of California local police officers to make arrests for violations of two provisions of the INA.

It is important to note that local police have no power to stop the enforcement of federal laws by federal law enforcement personnel in their states. They are not obliged to assist federal agents, but they can be arrested for impeding a federal investigation if they take actions to delay or prevent the lawful arrest of state citizens by these agents.

Local police can't arrest for unlawful presence in the US without special federal authorisation

In the United States, local police officers are generally not authorised to enforce federal law. However, there are certain circumstances where federal entities can extend power to local officials, or "deputise" them, to enforce federal law.

Local police cannot arrest individuals for unlawful presence in the US without special federal authorisation. Unlawful presence is not a crime, and only certain federal officers, such as immigration officers, can make arrests for unlawful presence. This is because the power to regulate immigration is exclusively vested in the federal government, which has established a national immigration bureaucracy—the Immigration and Naturalization Service (INS).

While local police cannot arrest individuals for unlawful presence, they can arrest for lawful entry under the same conditions that apply to state law arrests. For example, Connecticut law authorises state and local police to arrest people for violations of federal criminal law. However, whether they can legally make an arrest depends on whether federal law explicitly or implicitly allows them to do so for that specific crime.

In the case of Gonzales v. City of Peoria, the Ninth Circuit Court of Appeals held that federal law does not preclude local enforcement of the criminal provisions of the Immigration and Nationality Act (INA). This means that local police officers can be authorised to arrest illegal immigrants for violating the criminal entry provisions of the INA. However, this must be done in a way that does not impair federal regulatory interests.

Local police can be arrested for impeding a federal investigation

While local police officers are not authorised to enforce federal law, they can be arrested for impeding a federal investigation. Local law enforcement officials are not typically authorised to enforce federal law, except in specific cases where the federal entity with jurisdiction over the law extends power to the local official. In practical terms, this rarely makes a difference to offenders, as almost all federal criminal laws have a parallel state or local law. When an individual is arrested by a local official, charges are filed against the local statute, and federal charges may be filed later based on the evidence available from the local officer.

Local police do not have the power to stop the enforcement of federal laws by federal law enforcement personnel in their states. While they do not need to help federal law enforcement agents, they can be arrested for impeding a federal investigation if they do something to delay or prevent the lawful arrest of state citizens by federal enforcement agents. The US Constitution tries to make this a non-issue through the Supremacy Clause, which states that any state law in conflict with a federal law is unconstitutional and superseded by the federal law.

However, there are some areas of law, such as immigration, where the state does not have the authority to make any laws, even those in concert with federal law. Federal immigration law explicitly authorises state and local police officers to enforce various provisions of immigration law, including civil provisions, under three circumstances. Firstly, a written agreement between the US attorney general and a state or municipality in which state or local officers are deputised as immigration officers under federal supervision at state or local expense. Secondly, the declaration of an emergency by the US attorney general due to an influx of aliens. Thirdly, the enforcement of a specific criminal provision of the Immigration and Nationality Act (INA).

The Department of Justice investigates and, where the evidence permits, prosecutes allegations of constitutional violations by law enforcement officers. These cases often involve allegations of excessive force, sexual misconduct, theft, false arrest, and deliberate indifference to serious medical needs or a substantial risk of harm to a person in custody. The Department's authority extends to all law enforcement conduct, regardless of whether an officer is on or off duty, as long as they are acting, or claiming to act, in their official capacity.
