Modern security systems incorporate “Stop and Search” facilities. It became necessary for all subjects to be screened for contraband before they leave their work place. The present unofficial world record is held by a Platinum worker who placed 841 grams of Platinum (+- $ 42,000 US) in a single package in his rectum.
Innocent workers are known to be targeted and forced by crime syndicates to become couriers of contraband especially if there are no security measures (like Stop and Search) in place to prevent the smuggling of contraband.
