Harming a swan is treason to Her Majesty. You will be publicly drawn and quartered at the Tower of London.
This is so stupid. Canadian geese aren’t that nice either. Swans are slower and there are only two of them. Get a stick or fishing poll or dog and the Swans can be steered anywhere.
If you want problems, try skunks, bears, raccoons, coyotes, rats, termites, fire ants, killer bees, rattle snakes, moose or HONEY BADGER. Honey badger don’t care.
