I posted this in training as this is a real world incident where the homeowner is lucky to be alive. The guy finds a teen(teen with a record) inside his home and chose not to shoot him, and the teen then nearly disarms him as thanks...

Even though the pic shows a gun the class doesn't seem to cover those.
