The people who have toddlers and don't use high shelves with no crawl-up access, or something to shove toward the shelf to crawl up to it, should be shot and killed by toddlers.
All very well, however really a lot of the people shot are kids, random visitors, the toddler themselves or other toddlers. Toddlers don't tend to go hunt down the legal owner to enact some sort of darwinian karma, weirdly enough.
