If you get caught with more than 10K cash they can take it.
This is not anything new. Lesson here is do travel with that much cash unless you are willing to fight to get it back.
Usually, drug dealers don’t fight for the money.
If someone does fight for it, they have to prove where they got it. If they can’t, the government wants their share. That’s why you have to get creative about it.
Driving around with $48k of undocumented cash today is just ignorant.
