I'd settle for seizing all of Purdue's assets and pursuing criminal charges against any Purdue executives who were knowingly complicit in this calamity.  I'd want long prison sentences but, as a concession, I'd let the executives serve their time in a minimum security facility.  That would be a decent compromise.
