Every major star system that developed into a nexus of trade, services and tourism dealt with thousands of starships a day. From small pleasure yachts to massive fleet carriers, the amount and variety of ships that dropped into the Harkensen System far surpassed the patrol fleets of the Honored Ones.
A significant portion of the visitors dropping into this star system consisted of outfits looking to resupply their ships and mechs while sending their crew on shore leave. Ordinarily, the Reinaldan inspectors never really bothered to sweep the ships of the outfits very thoroughly. They primarily scanned for dangerous weapons. Everything else was free game.
How else would Harkensen's black and grey markets get their illicit merchandise? If the inspectors did too good of a job, all of the excitement in the underground markets would be gone!
