When an officer runs your name, the answer does not come from a courthouse. It comes from a database. LEADS carries Illinois entries; NCIC carries them nationally. What appears there determines whether you are released, detained, transported, or booked.
Replication is the multiplier
A local warrant record does not stay local. Fields entered by one county agency propagate into state and national systems, where officers in any jurisdiction act on them. An error in the charge description or category field does not stay in one office — it travels.
Validation is a legal obligation, not a courtesy
Agencies entering records into these systems are required to validate them periodically for accuracy and currency. Validation history is an administrative record, distinct from the substantive restricted returns, and can be requested on that basis.
The documented example
A July 15, 2026 Sheriff’s Warrant Details print describes a 2026 probation-revocation warrant using 2022 traffic charge lines with a Felony category. A July 29 FOIA to the Illinois State Police seeks the administrative data-quality and validation records. See the warrant record and the five confirmed sends.
