In reality, the likelihood of a child being snatched off the street by a complete stranger is so close to 0% that it isn’t anything you actually need to worry about. Most children who are kidnapped are taken by a relative, usually a parent.
In the world today, people won’t even let their kids play in the front yard. It’s ridiculous.
Speaking from experience, an electric goad hurts A LOT less than a branding iron.
