First off, I doubt their statistics, especially coming from the CDC. The CDC, NIH, AAP, ACP, AMA, and most other major health organizations are inherently anti-gun.
Secondly, they're talking about actually
SHOOTING someone in your home. The vast majority of defensive
USE of firearms does not entail SHOOTING someone. Merely mentioning you have a gun, racking the slide, displaying your gun, or even pointing your gun at an intruder is likely enough to end the scenario either by causing him/her to flee or freeze and wait for LEOs to come--and this
SHOULD be considered defensive use of a firearm.
Criminal justice statistics state that firearms are used defensively about 2.5 MILLION TIMES A YEAR, which outnumbers murders by far. Check out
this documentary on the Second Amendment by leading legal scholars from around the country.
Moreover, accidental shooting deaths are at an all time low in recorded U.S. history, according to one of the recent
America's First Freedom articles. Children are BY FAR AND AWAY more likely to die in a car, swimming pool, etc. than being accidentally shot by a gun that "just went off". John Stossel did a recent story on 20/20 regarding this, as well. It was within the last 6 months on ABC, and it put a lot of risks in perspective.
If parents are really concerned about risk of accidental death of their children, they should stop driving their kids to school or anywhere else before worrying about guns.
Finally, the RKBA is not contingent upon need, "sporting purposes," crime rates, accidental deaths, or any other "statistics," so all of this is irrelevant.
