This event reports routine administrative statistics (arrest numbers declining) without any constitutional mechanism, policy change, or institutional impact. A-score is 0 across all drivers: no election interference, no rule of law degradation, no separation of powers issue, no civil rights violation, no institutional capture, no corruption, no violence. The decline could reflect reduced crossings, seasonal variation, enforcement changes, or measurement artifacts - the ambiguity itself signals lack of substantive constitutional impact. B-score is minimal (2.55): slight outrage potential for immigration-focused audiences, media-friendly statistics, timing relevance to ongoing border debates, pattern-match to recurring immigration coverage, but no novelty or meme-ability. Classification is Noise due to A<25, no mechanism specified (null), and multiple noise indicators: routine statistics release, ambiguous causation explicitly noted in summary, purely administrative data without policy or institutional change, narrow population impact.
