This event involves 60 veterans detained during a protest against an Army parade on Capitol Hill with one injury. A-score: Civil rights (3.5) for protest detention and assembly restrictions, rule of law (2.5) for law enforcement response, violence (1.5) for injury. Mechanism is norm_erosion_only (0.6 modifier) with narrow population scope. Severity modifiers near baseline given temporary detention nature. Final A=5.82 (well below 25 threshold). B-score: Moderate media friendliness (veterans protesting military parade) and outrage potential, but limited novelty. Four identical articles suggest coordinated but low-effort amplification. Final B=12.99. Classification: NOISE - A-score far below threshold, weak mechanism (norm erosion only), narrow impact, routine protest detention scenario, and suspicious article repetition pattern indicate this lacks constitutional significance despite modest hype.
