Supreme Court Justice Antonin Scalia on Sunday renewed his criticism of Chief Justice John Roberts' reasoning in upholding President Barack Obama's 2010 healthcare law and also said the Constitution undoubtedly permits some gun control. Scalia joined in a sharply worded dissent on the day of the June 28 ruling and added to his criticism on Sunday."There is no way to regard this penalty as a tax. ... In order to save the constitutionality, you cannot give the text a meaning it will not bear," Scalia said. "You don't interpret a penalty to be a pig. It can't be a pig."
