Sorry c2c- the Bucks may have given the money for the cards in this case (not sure how financing worked with the countless other sets), but the set itself was distributed by the police. There are also police sets that are clearly sponsored by companies (such as life insurance companies, oil companies.)
Even if, as they say in court, there is a preponderance of evidence exists that every police set was funded and distributed by the local team in question, for the sake of clarity, I believe they should be considered "oddball," and not team issue.
Team issues should be the postcards, photocards, cards, and photos printed and distributed by a team for fan mail responses, press/media use, charity, or team store sale.
