In the field of information security at the natsec level, you can do one of two things. First, you can try to hide a piece of info through stealth and avoidance. Or, you can hide it in plain site, surrounded by more easily detected but innocuous targets.
Law enforcement agents are curious, but lazy. If you plant hemp plants all over a region in large patches, and put your grow in smaller areas spread out, they will quickly reach their "objective", their numbers will look good, and they won't hunt as hard.
They really don't care how they reach their numbers. They just want to look good on paper. Put in a bunch of honey pots, and they will get distracted.
Human nature.
