Single violent incident at protest with political symbolism. A-score: violence(4) for physical assault, civil_rights(3) for targeting political protesters, rule_of_law(2) for criminal act. Norm_erosion_only mechanism yields 0.4 modifier - no institutional change, just behavioral boundary testing. Single_state + narrow population = 0.7 scope. Severity: high reversibility (isolated incident), low durability (no lasting institutional impact). Final A=3.72. B-score: extremely high outrage potential (political violence + child victim + immigration controversy), strong media appeal, clear symbolic framing (Trump flag). Layer 2: high mismatch (individual crime vs constitutional threat), strong pattern-match to political violence narratives. Intentionality moderate (7) - symbolic display suggests performative element. Final B=32.45. Delta=-28.73 strongly indicates List B: high-hype distraction from isolated criminal incident with no constitutional mechanism.
