"The ATA is contacting all 200 Trading Standards departments, run by local authorities, to ensure that officers are aware of the law and the need to prevent illegal lead weights being offered for sale."
Perhaps the ATA could better spend their time and money questioning why it is that only (?) the UK finds it necessary to ban lead shot in the first place and getting a lobby together to overturn the ruling which will then allow their own members to profit from these sales.
I wonder if any studies have been done to discover if numbers of birds sick with lead in their crops have declined since the ban was introduced. No? Well start there then!
