Stupid bank structuring laws that allow the government to seize your property without due process if they don't like the size or pattern of your cash deposits. All in the name of going after drug dealers.
I run a cash business. It is not at all unusual that we might have $9000-ish a week deposits through the summer months at certain large locations. If some bored Fed were to decide tomorrow that these looked suspicious, they could seize all my bank accounts, effectively bankrupting my business, and then force me to try to get my money back in the courts (where the burden of proof is on me, not the government). All the while with a set of incentives such that the Feds get to keep any of my money for their own departmental use if they thwart my efforts to get it back. And all without any need to go to a judge to sign anything or even offer a shred of proof that I am engaged in an illegal activity. Making deposits just under $10,000 is effectively a crime in and of itself, and the only thing that protects me from abuse is my hope for the goodwill of the Feds that they won't abuse their power.
This is the kind of Faustian bargain we have made for ourselves in the war on drugs, and it needs to end.
