I know a similar story of someone finding 3.5 grams

a friend of mine bought a bag and drove to the most secluded area, behind some indoor courts in a seemingly abandoned carpark, to his luck police pop up, do a full search of the car looking in and out until they finally find his bag hidden away, they have him hold the bag up and take a photo then drive off,
they were never seen again, no fine in the paper, no court order, nothing xD
they just robbed him, took a photo of his face with their "loot" and disappeared
