Supremacy clause is irrelevant. State murder charges will stick--no federal forgiveness.

No, it's different. The difference is why many states don't want local officers assisting ICE officers. Marco and Dope will insist there is no difference or trivialize it, so they can criticize states for not cooperating. But why should a state expose its officers to liability when they don't have to? What are the odds on Trump agreeing to indemnify a blue state?

ICE (Immigration and Customs Enforcement) officers and local police both generally enjoyqualified immunity—a legal doctrine protecting government officials from being held personally liable for constitutional violations (like excessive force) unless they violated "clearly established" rights.

However, ICE officers, as federal agents, possess additional layers of protection—often referred to as federal immunity—that make them much harder to hold accountable than local police.

Here is the breakdown of the specific protections ICE officers have that local officers generally do not:

1. The Supremacy Clause and Federal Removal

What it is: Under the U.S. Constitution's Supremacy Clause, states cannot interfere with the federal government’s ability to enforce
federal law.
The Difference: If a local officer commits a crime (e.g., assault or manslaughter), they are prosecuted in local or state court. If an
ICE agent commits a crime while on duty, federal law allows them to move the case from state to federal court (removal).
The Impact: Once in federal court, the case is handled by federal prosecutors, who may be less likely to pursue charges against their own
agents, essentially shielding them from state-level accountability.

2. Heightened Difficulty of Civil Suits (Bivens vs. 1983)

Local Police: Individuals can sue local officers under 42 U.S.C. Section 1983 for civil rights violations.
ICE Officers: There is no equivalent statute for federal agents. Instead, lawsuits must be brought under a Bivens action (named after a
1971 Supreme Court case), which the Supreme Court has significantly narrowed over the years, making it far more difficult
to sue federal agents for constitutional violations than local police.

3. Federal Representation and Indemnification

Defense: When sued, ICE agents are defended by the Department of Justice (DOJ).
Judgment:If a judgment is reached against them, the federal government almost always pays (indemnifies), whereas a local officer might
face personal financial ruin in rare, egregious cases.

4. Limited State Authority to Arrest

The Difference: Local law enforcement cannot legally stop or arrest ICE officers for performing federal duties.
The Exception: While local police have a duty to intervene if they witness excessive force, they cannot interfere with or block an ICE
agent's lawful, or even reasonably perceived lawful, enforcement actions.

Summary of Differences

Feature...................Local Police.................ICE Officers (Federal)
Prosecution............State/Local Court............Federal Court (often)
Lawsuits.................42 U.S.C. § 1983 (easier)....Bivens action (harder)
Liability Defense.....Qualified Immunity...........Qualified Immunity + Supremacy Clause
Immunity Type..........Qualified....................Qualified + Practical Immunity

Note on "Absolute Immunity": While some officials have claimed ICE officers have "absolute immunity," experts clarify that this is not technically true in a legal sense—they do not have blanket permission to break the law. Instead, they enjoy a combination of qualified immunity and strong jurisdictional protections (supremacy clause) that make them effectively immune from local, state-level scrutiny. SNIP
