To play devil's advocate for a moment, if I'm a criminal in the drug business, and I've got a bunch of money on me when you stop me, by the time you meet the burden of proof, I won't have the money any more. If you're going to seize it at all, you have to seize it when you've got the chance.

The best we might realistically ask for is that I get it back once the police can't meet the burden of proof...
