Both Special Branch and HMC&E are regular, if infrequent, visitors to our strip. I think it gives them an excuse for getting out of the office and also SB admitted that they wanted us on their side as we would spot unusual movements long before thay heard about them.
SB also, about a year or so ago, collected all the names and addresses of owners at the strip together with their car registration numbers. Said they were entitled to do this under the ANO. Didn't argue with them at the time but no effort has been made by them to keep the information up to date.
