Fear of Retaliation ?

Some people might think that some motorists will take exception to our actions.
Do not fear.
The approach we make is to remind motorists that a speed limit has been posted for a reason. We simply are there as an aide-memoire.

In case anyone does approach those taking the readings we have a letter they can read to explain why we are there.

Upon reading this simple document, any objections would have been washed away.
In case of objections still being voiced, those taking the readings are advised to remove the Speed Check signs and walk away.
In truth, so far no objections have been voiced what-so-ever and those motorists who have stopped have applauded our actions.
