Define possession
You don’t have too many situations where a legal gun owner says to his buddy that can’t possess a gun;
Hey, hold this for me while I [do whatever]
Just to muddy the waters some more, take a look at Henderson v US, 135 S.Ct. 1780 (2015). Henderson's guns were seized by the FBI, he pleaded guilty to a felony, and tried to transfer his guns to his friends. The FBI argued that releasing the guns would give Henderson constructive possession, in violation of 18 USC 922.
What if Henderson owns a company with private security? Can the company buy firearms for its employees? What if he's a stockholder of a company with a private security force? What if a company where he's a stockholder sets up a private security force? Is he now in constructive possession of a firearm as a felon?
What if a convicted drunk driver owns a company? Can the company buy company cars? What if a convicted DD buys a cab company so he'll have drivers available at all times? What if he owns stock in Avis?
What about Joe Walsh?
