Way to ignore suicides, accidents, children accessing guns in the home and all the other bad things that happen that wouldn't happen if people didn't have guns laying around
I would've thought the events of the last few months would've put to rest this flawed line of logic. The folks saying "guns don't kill people, people kill people" were right. If you take away access to guns, people don't magically become non-violent and pacifist subjects. They figure out other ways to accomplish their goal of killing people. Like build bombs, or drive a truck into a crowd. These things still happen.
The number of people killed in the U.S. in 2013 from accidental discharge of firearms was 505. By contrast, the number of people killed by drowning (mostly in pools) was 3,391. 2,780 people were killed by fires. The number of people killed by going to the hospital was 2,768. Heck, the number of women killed due to complications from pregnancy was 1,138. All of these are a much bigger danger than gun accidents. You just have a warped view of the relative size of these risks because the media disproportionately over-reports gun accidents (probably because most of the people who work in it would like to see the 2nd Amendment repealed). If their reporting reflected the actual statistics, every single news story about a child accidentally killing someone with a gun would be accompanied by 7 stories of a child drowning in a pool, 5 stories of children dying in a fire, 5 stories of children dying due to a botched surgery or mistaken treatment at a hospital, and 2 mothers dying while giving birth.
21,175 people committed suicide by gun. But 19.974 people figured out some other way to kill themselves. So it's pretty safe to say banning guns wouldn't affect the suicide rate in the slightest.
The 11,208 murders by gun are the only area where the argument holds some ground. 4 people were only wounded in the Wurzburg train attack because the perpetrator only had a knife and axe. 1 person was killed and 5 wounded in the Reutlingen attack because the perpetrator only had a machete. If they'd had guns, the toll probably would've been higher. But it's foolish to think the number would've been zero (4,913 people were murdered without a gun). And 29,001 people were killed due to alcohol, 30,208 people were killed due to falls, 35,369 from car accidents (some overlap with the alcohol stats), 38,851 from overdoses and poisonings, 41,149 from suicide. If your goal is saving lives, all of these are much more important issues we should tackle first, before gun violence.
Fundamentally, violence, terrorism, and suicides (which account for 97% of gun deaths) are social problems. Eliminating the tool via which people are acting out on those problems doesn't make the problem go away. These things will still happen. Just not with a gun. This is a common logical error made by people with bleeding hearts (I won't say liberals because many conservatives make the same mistake too). They don't want to hurt anyone's feelings by blaming people for having faults, so they instead shift the blame onto other inanimate things that have no feelings. Like rap music, or playing too many video games, or porn, or frat parties, ... or guns.
To address these problems, you have to tackle the root social cause. Which is hard, scary, will hurt lots of people's feelings, and there's little consensus on what's the best way to tackle them. So nobody wants to do it that way, when you can take the easy way out and convince yourself that some inanimate object is the root cause, and that eliminating that object will cause all those other problems magically go away.
