Defensive Immunity

4 min read

Definition

“Defensive Immunity” is the term GovFacts uses to distinguish a novel federal posture from traditional Supremacy Clause Immunity. Traditional immunity is asserted after a state files charges, in federal court, with the federal judge determining whether the officer’s conduct fell within federal authority. Defensive immunity is the preemptive move: federal officials block state investigations before charges are filed, withholding evidence and asserting exclusive federal jurisdiction, so that the state never reaches the point where immunity can be litigated. The distinction matters because traditional immunity has narrow historical exceptions; defensive immunity treats those exceptions as irrelevant by ensuring investigation never happens.

Why It Matters for the Newsletter

This is the doctrinal move at the center of the Renée Good / Alex Pretti accountability story. It is also the direct through-line to Justin’s “Trump Is Covering Up the Minneapolis ICE Shooting (Just Like He’s Covering Up Epstein)” and “Constitutional Gymnastics” pieces. The administration is not making the traditional Supremacy Clause argument — that, properly litigated, would put actual video evidence in front of a federal judge. Instead it is making the structurally broader claim that states lack jurisdiction to investigate at all, which if accepted would transform Supremacy Clause immunity from a narrow, rebuttable protection into a categorical investigative blackout.

Evidence & Examples

  • The Good case: Federal government initially agreed to joint investigation with Minnesota BCA, then reversed after public statements by Trump administration officials. FBI revoked Minnesota BCA’s access to evidence. DOJ refused civil rights investigation When the Federal Government Blocks State Murder Investigations
  • The Pretti case split: Federal government opened civil rights investigation but refused to share evidence with Minnesota — a “departure from past administrations’ standard procedure” Minnesota sues to obtain evidence in shootings by federal officers during ICE surge
  • The “Touhy letter” standoff: Formal demand letters with Feb. 17 deadline; FBI notified state Feb. 13 it would not share Pretti materials; no materials provided more than a month past deadline Minnesota Kicks Off Legal Battle With Trump Administration to Hold ICE Shooters Accountable
  • The George Floyd counter-example: State and federal authorities ran parallel investigations of Chauvin; neither side claimed exclusive jurisdiction; the contrast with the Good case is “stark” When the Federal Government Blocks State Murder Investigations
  • Prosecutor resignations: Senior DOJ Civil Rights Division prosecutors resigned in protest; 33 former federal prosecutors in Minnesota (many Republican-appointed) issued an open letter arguing the posture is abnormal
  • Private litigation as fallback: Good family retained Romanucci & Blandin — the George Floyd family’s firm — because no prosecutorial track is available
  • Historical precedent: Article emphasizes “what has not previously been attempted — or at least not on this scale — is federal officials blocking investigations before charges are even filed”

Tensions & Counterarguments

  • The federal side frames evidence-withholding as protecting agent identities and ongoing federal investigations — not as blocking state prosecution
  • In the Pretti case, DOJ did open a civil rights investigation, suggesting the federal posture is not uniform abdication; it is selective
  • Traditional Supremacy Clause immunity would still apply if the case reached court; defensive immunity simply saves the federal government from having to litigate that case
  • There is no Supreme Court precedent directly on point — the doctrinal position is novel rather than clearly unlawful
