I think the only downside to this is that if I had expendable cash already liquid so no paper trail, and I was a juror, and I wanted the defendant to get in even more trouble, I could claim the cash was a bribe and get it back with no risk. It would also make laundering money easier as any claim of bribery instantly cleans up the source of it. And if the designated grunt does his time and doesn’t talk, it never gets traced back to the source.
