My favourite(just slightly edited) quote from the BASC reply concerning not allowing guns to be visble in gunshops to the passing public.
"It would be farcical to ask a Second World War reenactment
group to refrain from carrying firearms during its presentation to the public in case their guns had a baleful influence on the young. Such a notion would be akin to requiring classical ballerinas to wear trousers on the off chance that their exposed legs might cause undue excitement to young men in the audience. Or even asking athletes to wear duffle coats lest they happen to be peanut smugglers"
