Varmints and Scoundrels Beware

My brother-in-law doesn't want any intrusion into his garden by pests or people. To that end he erected this warning to all those who would remove his property without permission. The store maniquin looks real enough, as does her pretend gun, that no deer or other night visitor has yet been brave enough to attempt to steal his tomatoes!
Makes me wonder if I shouldn't try to get a dummy of my own.
