The best self defense weapon is a dog. The chances of someone entering a home with a dog are significantly lower in comparison to the gun owner. The stats also show that a residents gun is more likely to kill the owner or the owners family than it is an intruder.
I found it very interesting that you set two different statistics for different things (dogs as a deterrent vs firearms as a liability) without their corrilary points.
More children under 12 are attacked by dogs than any other age group... and it's usually the family dog(1). In just one city (Pontiac Michigan) there were 53 attacks by dogs which resulted in which dogs had bitten the victim's several times causing stiches and /or servere injury(2). In a cite with a mere 66,000 people (12), this would extrapolate to 236,000 severe injuries inficted by dogs in the US every year. In the US, there are more than 20 fatalities a year, though this number is very small compared to the number of non-fatal maulings. Like firearms, you are most likely to be bitten by your own dog (3).
There is a higher listed accidental death rate for firearms (600 in 2000) though there is a far lower incidence of non-fatal injuy at 18,000 (12). Further, it's often asserted that many of the "accidental shootings" are suicides, and some homicides. (see also my statistics by age later in this post).
To put this is perspective: the 600 childhood deaths from accidental gunshots in 2000 compare to 22,300 dealths from cars, burns, drowing, and poisons (4). Further, most of the accidental deaths (70%) occur in children 15-19 years of age (11). To me, this implies poor instruction on the part of the parents. It's a problem, not with firearms, but with education.
I've been trying to track down an accidental fireamrs death rate for Switzerland, but without success. Ayone got one?
But the other part of your comment is the effect on crime. For that, I'd point to two instances where a juristiction changed gun ownership laws. First Australia, where in 1996 the government seized most of the populations firearms. In some areas, this resulted in a 300% increase in homicides with firearms. Roberies increased 60% the following year. Two years following the gun ban/confiscation, armed robberies rose by 73 percent, unarmed robberies by 28 percent, kidnappings by 38 percent, assaults by 17 percent and manslaughter by 29 percent. (7)
In contrast, I present Kennesaw GA (8). In 1992 Kennesaw passed a law which required homeowners to own firearms. The year that the law went into effect, crime against persons plummeted 74%. The next year is fell an additional 45 percent (9).
The effecacy of firearms is undeniable, with a successful use ever 13 seconds or so (10). Having had a friend raped with her dog in the next room, I'm a little more suspect of the true efficacy of a pooch.
