I'm only an engineer; I know nothing at all about the legal
implications. The detector van simply confirms that a TV receiver is
being used at a particular address, precisely to what use that
information is put I cannot speculate. Obviously it must be
considered of considerable value to justify the substantial
modifications to the vans and the installation of some quite expensive
equipment.
