Young children up to the age of eight or so have to be protected from any sort of risk/danger around the home. Sensible parents make sure that sharp tools, dangerous chemicals such as bleach etc, even window- blind cords in a loop, garden ponds and pools, plastic bags, open fires are inaccessible and safely locked away or guarded. Most parents assess their home automatically for dangers and keep their children safe. What they don't do ( well, not here in UK anyway) is hand over to a small child a working firearm, explain how to use it and leave it lying around charged with ammunition. It's preposterous and almost incredible that any parent would even consider such a lunatic thing. I'm so sorry the little girl was shot and killed, but really, they were just asking for a terrible tragedy to happen. I only hope they can forgive themselves in time, and come to terms with the loss of a little innocent tot. Very, very sad.
