I live near a river which has plenty of wildlife on it including swans and ducks. Over the last few years, we've had a massive rise in Catapult Killing youth, which target the swans and ducks in particular. The local community are really angry about this and the police have been involved at times. It has got to the point where people are talking about vigilantism on local facebook groups to try to tackle it. The youth have been filmed doing it but just wear hoodies and masks and run off into the woods or back home. Facebook groups takes down any posts about it to protect them from exposure when people take pictures or videos.
