Visions of the LAPD’s Rampart Division, where the cops robbed the drug dealers.
That's a good point as well. However, I was thinking more about that one person who was a licensed landscaper and flew down to SoCal with as I recall about fourteen thousand US dollars to purchase some equipment and have it shipped back home, and the local LEOs "Arrested" the cash because it was potentially "drug money" -but did not arrest the poor fellow himself.
I don't recall what happened later, if he ever got his money back, but I seem to recall that it dragged on for quite some time and no one seemed to follow up on it as time went by. I think he had to get a lawyer, who as anyone knows do not come cheap, and had to endure more than a couple of hearings and delays, since no one seemed willing to simply let go of an easy acquisition of not-dangerous-to-acquire revenue.
