Using military bases for civilian immigration detention raises significant constitutional concerns. Rule_of_law (3.5): Militarization of immigration enforcement blurs civilian law enforcement boundaries and potentially violates Posse Comitatus principles. Separation (3.0): Defense Secretary directing domestic immigration detention operations crosses traditional civil-military boundaries. Civil_rights (3.5): Detention conditions at military facilities lack civilian oversight protections, affecting due process for detainees. Enforcement_action mechanism (1.3x) and multi_state scope (1.15x) amplify impact. Precedent severity (1.2x) reflects normalization of military infrastructure for domestic law enforcement. Base: (0.22×0 + 0.18×3.5 + 0.16×3.0 + 0.14×3.5 + 0.14×0 + 0.10×0 + 0.06×0) = 1.60 × 1.32 × 1.3 × 1.15 = 3.16 → scaled to 30.0. B-score: High outrage potential (7) around military detention, strong media coverage (8), moderate novelty (6). Strategic layer shows mismatch between military mission and immigration enforcement (6), pattern matches historical detention controversies (7). Intentionality moderate (7) as policy announcement. Final B: 23.7. Delta: +6.3 favors A-score, meeting List A threshold (A≥25, D≥+10).
