Airport baggage screening officers required to use BWCs for Red channel interactions with 30-day recording retention. BWCs must be worn by officers processing passengers in the Red channel to record baggage examinations from the officer's perspective; recording begins on arrival/diversion to the Red channel and stops only with the Air Customs Superintendent's permission. A register records wearing, removal and handover, supervised transfer of data to a password-protected internal drive, daily hard-disk backup, and a minimum 30-day retention. BWCs are for official use only and weekly random reviews and monthly supervisory reviews with reporting obligations are required.
