And if by lawn ornament, you mean my car? And the perp is threatening me with bodily harm if I try to stop him?
Horse thieves used to be summarily hanged.
If the thieves realize how important personal property is to those from whom they would steal,
maybe they would get a real job instead?
They can have my garden gnome when they pry it from my cold dead hands.
It’s my garden gnome, paid for by my getting up every morning and going to work.
Anyway, not sure a blast of rock salt in the butt is fatal. May keep someone from sitting on it & plotting crimes
