You're missing the point: here in America you're *supposed* to be able to "do things that make you look like you are hauling drugs". You're supposed to be able to do whatever you want, as long as it's legal, no matter how illegal it looks.
Let's say I look like a burglar because I locked my keys in the house and now I have to climb in a window: the police have every right to stop me. If I'm (somehow) using my wallet to try and jimmy the window open, the police have a right to seize that wallet. But once I've shown that I'm not a burglar, I should get my wallet back.
The point of this article is, that's not actually how it works. From TFA:
"You’ll have the right to seek its return in court, but of course that will mean big lawyer’s fees, and legally documenting exactly where the money came from. You will need to prove you are not a drug dealer or a terrorist.
It might take a year or two. And several trips back to the jurisdiction where you were pulled over. Sorry.
In places like Tijuana, police don’t make any pretense about this sort of thing. Here in the U.S., though, it’s dressed up in terms like “interdiction and forfeiture,” or “the equitable sharing program.”"
