Local mayor arrested at ICE protest scores low on constitutional damage (4.7): rule_of_law driver=2 (enforcement_action mechanism but routine arrest, no systemic breakdown), civil_rights=2 (protest rights exercised, arrest appears procedural). Severity multipliers reduced (0.8/0.8/0.9) as arrest likely temporary/reversible with minimal precedent. Mechanism modifier 1.1 for enforcement_action, scope 0.7 for local/narrow. B-score high (26.2): Layer1=55% of 28/40 (high outrage_bait, media_friendliness, novelty of mayor arrest), Layer2=45% modulated by intentionality=9 (staged protest characteristics, media coordination evident in 8 articles covering local event). D-score=-21.5 strongly negative. Classification: List B (B>=25 AND D<=-10). This is political theater with high media amplification but minimal constitutional impact.
