I think I'd have been more comfortable with a 7-0 unanimous verdict that set up a series of tests for when the government can/can't withhold assets from legal defense teams than I am with the 5-4 outcome that gives prosecutors blanket discretion to confiscate criminal proceeds. But I'd be equally uncomfortable with a 5-4 Blackmun opinion saying that the right to fund attorneys is inviolate, as that produces an incentive to double down on criminal enterprises to build warchests of legal defense funds.
Generally, I want criminal conspiracies to be shut down. I think that's the reasonable-people consensus.
