I couldn�t agree more, sir.prize. However, your question was whether the practice was unscrupulous, not whether it is the best use of police resources.
I also completely agree with kempie. In particular the second photograph shows the van to be parked in what appears to be an acceleration lane from a slip road � highly dangerous. Most dangerous of all in my opinion is the van perched in the central reservation of a dual carriageway.
Unfortunately the website does itself no favours. Its general tone is offensive but in particular it sets out to give the impression that excess speed is perfectly acceptable provided you are not within range of a detection device:
�...to catch motorists who speed up after passing a Gatso�.
�...but is parked just before a fixed camera. This is one of the meanest tricks of the scamera partnerships...�
And so back to my burglary analogy � it is similar to suggesting that undetected burglary is acceptable.
It is true that the Safety Camera Partnerships seemingly devote huge resources to catching their offenders compared to that spent catching burglars. However, people who have seen loved ones killed or seriously injured because of excess speed may disagree.
