Breaking news banner errors are going to happen. No one can be perfect all the time. And if it’s a small typo, it’s usually identified and fixed promptly. Not a huge deal. When you report a person has pleaded guilty on five counts of manslaughter and they haven’t, well, that’s a problem. When that person is Paul Manafort, people are going to wonder how they possibly missed that development.
ABC did just that earlier today and, obviously, regrets the error.
UPDATE: It did not go unnoticed.
