'Brave' Kentish 'Hunters'

A pretty horrific story of a family of Mute swans (the pair with 5 cygnets) being slowly massacred in Kent by a person or persons unknown, before being put in plastic bags and thrown into a stream (https://www.theguardian.com/music/2018/dec/02/killing-of-swan-family-in-kent-brings-calls-for-airgun-regulation). Apparently, that county has a very high incidence of airguns being used on wild animals (apparently, even grass-eating birds).There seems to be a good case for regulating the ownership of these weapons.
