There are also laws against as you said second hand smoke by designating where you can smoke, still 40,000 deaths a year from it. How about drunk driving?
According to these people: http://dui.lifetips.com/cat/61352/dr...ats/index.html
Around 16,000 die from drunk drivers every year, that's like 30% more than the from guns and it includes innocent families driving home from grandmas house.
The difference is that there are no upsides to all these other ways of death. Where as statistics shows responsible gun owners use these guns to protect themselves and stop crime and that happens 24/25 times. There might be a case for guns to be made illegal if they simply weren't so much more beneficial than dangerous. With guns made illegal there would be more deaths, more crime and few ways to protect yourself.
