Why on earth would anyone buy their kids one of these? Last year my MIL window was put through - a small hole - had no idea what it was until recently when loads of ducks and swans are being attacked in our park. Dozens killed and maimed. It's totally disgusting.
Jeez parents - surely you know these are actual weapons?
YABU - it's just Dennis the Menace kids fun innit
YANBU - it's only a matter of time before kids start losing eyes
