It wasn't just a poor picture, it was a video. The driver explained several times that he was queueing in traffic and it was only when he refused to accept the ticket and demanded his day in court with the camera operator present that the council backed down. That's why it's news.
What he was thinking was "My job is in danger if I don't issue enough penalty notices". Wardens don't get a pay incentive for issuing notices, but their failure to issue a certain number may suggest to their employer that they are shirking.
It doesn't look as though much "thinking" was used here. But then, motorists have for a long time been regarded by our glorious leaders as an easy source of income.
Fred, that wasn't the case the other day, according to one recent tv news report, that many of the parking enforcement officers were getting pay incentives for the amount of tickets issued.
It wasn't a traffic warden or a parking enforcement officer 'on the beat' - it was somebody sat in an office viewing the images from the mobile camera.
I suspect the image was sent direct to their office where, as hc suggests, a 'clerk' issued the notice. In fairness it is a pretty bad picture. So, a mixture of technical and human error.
It may be that the camera took the picture automatically. Driver gets back to office. Info is downloaded. Clerk looks at (poor) picture and issues notice.
