Same way they did it up here I would guess. Child shot with an unlicensed firearm and the Andrews law was put in motion .

This proposal is already in place
Making it an offence to fail to lock up an air weapon and its ammunition separately in the presence of under-18s while not in use
It's been in place since 2011 at least.
From 10 February, owners will be liable for a fine of up to £1000 if they do not take reasonable precautions to stop unauthorised access to their airgun by people under the age of 18. Safety leaflets informing new owners of the offence will be also be included with every air gun purchased.
500,000 in Scotland they claim is small fish to the 4 to 6 million airguns they claim in England and possibly includes Wales.
