Johann Hari and unethical journalism

Bagehot is unimpressed with Johann Hari's display of contrition:

So here is my take on Mr Hari. On reporting trips on the other side of the world, far from the watchful gaze of his editors, he plagiarised and embellished quotes (though he still denies accusations of inventing some of his most dramatic facts). Now he is admitting to wrong-doing and apologising, but only after getting caught, years later. [...] What does that say about British journalism?
