The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2024.

Read together — 42% complaint, 58 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$10.6M of Kings, written across 1,182 government filings.
