That wasn't at issue. Jim Jefferies claimed that armed self-defense is ineffective, and it takes just one example to rebut his (unevidenced) ranting ... sorry, satire (perhaps sandwiched between a stream of rape jokes, all totally ironic, natch).... We can all get emotional about individual cases. How about linking to the story of the small child who shot his sister? ...
Since you raised it, taking the data most favourable to gun control, around 100 children die from accidental shootings per year. This pales compared to the number of children who drown (983 in 2009), who die in automobile accidents (7,497, same year), or who die in fires (682, data from CDC, table on p.272). Each and every one of those deaths is a tragedy, but if childhood death is the concern, there should be equal focus on restricting access to swimming pools, cars, and fire risks.
All the arguments from the "most likely to die" reports fall down in the inappropriate application of generalized data to a particular where it just don't fit, since crucial variables like criminal background and suicidal ideation skew the figures, and don't apply to responsible citizens of sound mental health. As for whether guns are effective self-defense tools, research by Kleck & DeLone found not only that armed resistance is the safest course of action (pp.69-71), but counter-intuitively in the extreme, victims robbed with a gun face the lowest risk of injury!
