Let’s get one thing out of the way: it’s not normal to stuff $100,000 in cash into a suitcase and then check said suitcase on to a domestic flight. It’s extremely weird, in fact, not something you’d expect a typical person to do in their lifetime. However, doing so is emphatically
People sometimes carry tens of thousands of dollars in cash to buy cars in-person. It’s more common than you think.
So they can advise where the cash comes from. The problem wasn’t carrying it it was not been able to give an adequate explanation as to its origin.
That process requires a lengthy and expensive court case and even then sometimes they don’t get the cash back.
Also even if they give an immediate explanation to the officer they are pretty much guaranteed to take the cash anyway. The cop has a financial incentive to do so and will assume the victim is lying.
The cops don’t care, they’ll claim you’re lying and take the cash anyway.
This poor fool thinks the cops give a fuck what you say or what proof you have.
The possession of the money is treated as probable cause. The police are not tasked with finding the ultimate truth of things, just acting on probable cause.
So you’re on the road with $10,000 in cash. The police find out. You tell them the true reason. They write it down, then seize the money because it was suspicious to you to carry $10,000 in cash.
Then, of course, you can go petition to get the money back. At which time, you have to prove by a preponderance of evidence (the same bar as if you were suing them for damages) to get the money back.
the explanation you get to give to the judge as you now get to fight for your money back. the police officer is under no obligation to even listen to you as he steals from you.
