Don't get me wrong, I'm a huge objector to society becoming cashless, and I still generally use cash for most day-to-day purchases. I also think (as I'm sure everyone here does) that the civil forfeiture laws are some horseshit.
BUT
Why the fuck is dude flying with 40k??? You're telling me a small-business owner (albeit VERY small, according to the article) doesn't have a bank account? I feel like the Phoenix auction site or whatever was probably kind of shitty, and offered him some discount for paying in cash, which would be pretty shady for that big of a purchase. I just can't imagine cash being that dudes idea. I'd be shitting bricks flying with that much.
Also, could he not find a similar deal a little closer to home? Is Phoenix a hotbed for used big-rigs? Mumbles any knowledge of this? The whole story outside of the forfeiture just baffles me.
