I've made a few errors of judgment in my time, Some of them big, some of them small:
The other day I did a short journey on my bike - it was drizzling but I didn't bother with my waterproofs - and I ended up getting soaked. Or, I was depressed in my work for several years thinking it was too late to make a career change - then it was forced on me and now I regret not doing it earlier. Both these things were errors of judgement. That is to say I thought about what I was doing, made a decision and in good faith, got it wrong.
However I didn't send a series of misogyist emails (like Football boss Richard Scudamore) or recite a racist nursery rhyme on TV (like Jeremy Clarkson) or misuse public office for private gain (like my own local Labour mayor Sheila Peacock). And yet all these people within the past few days have claimed to make an 'error of judgment'.
Let's get it right. These people fucked up. They didn't have the misfortune to make a wrong decision in good faith. Their dark and deep-seated arsehole-ness was just publicly revealed for all to see .
