Supreme Court argument in Henderson
The government's "constructive possession claim didn't get very far. The government had been contending that designating to whom the firearms could be transferred was "control," and hence exercising illegal "possession." Then before argument they conceded that Henderson could transfer them to a licensed dealer. Looks like they didn't prepare for "if his transfer to a dealer isn't possession, how can his transfer to a nondealer be possession? There's no difference in terms of exercising control"?
