A-score: Violence driver scores 3 (isolated incident at protest, one victim, no systemic pattern). Civil_rights scores 2 (protest context involves immigration policy opposition). Rule_of_law scores 1 (criminal act, but standard law enforcement response expected). No mechanism specified reduces modifier to 0.7. Local scope with narrow population yields 0.6 scope modifier. Severity multipliers reduced (0.8/0.9/0.8) for isolated, reversible incident with minimal precedent. Final A=0.54. B-score: Layer1 high on outrage_bait (8, violence at political protest) and media_friendliness (9, dramatic visual story with clear political angle). Novelty moderate (5). Layer2 elevated on mismatch (7, single stabbing framed as broader protest violence pattern) and timing (8, during Trump immigration policy implementation). Intentionality moderate (7) for amplification of isolated violence to characterize protests. Final B=28.49. Delta=-27.95 clearly indicates List B classification.
