There's no need to construe a statement in 18.2-308 to mean that the CHP is public information. It's plain as day right here in 17.1-208:
§ 17.1-208. Records, etc., open to inspection; copies; exception.
Except as otherwise provided by law, any records and papers of every circuit court that are maintained by the clerk of the circuit court shall be open to inspection by any person and the clerk shall, when requested, furnish copies thereof, except in cases in which it is otherwise specially provided. The certificate of the clerk to such copies shall, if the paper copied be recorded in a bound volume, contain the name and number of the volume and the page or folio at which the recordation of the paper begins and may charge a fee therefor pursuant to § 17.1-275
. No person shall be permitted to use the clerk's office for the purpose of making copies of records in such manner, or to such extent, as will interfere with the business of the office or with its reasonable use by the general public.
So tell your representatives about 17.1-208 and maybe they'll understand.
