The point being this is how people use statistics to propagate pure BS.
This is a good point. One-way people miss use statistics is to draw conclusions far beyond what the numbers can support. For instance, many people look at the statistics of accidental/criminal use of home-kept firearms being more prevalent then self defense shooting, and draw the conclusion you are safer in a home without a firearm then you are with one.
If you look at the details of accidental/criminal shootings, it is clear this conclusion is not true. Accidental/criminal shooting generally involve careless handling or storage. If you follow the 4 rules of firearm safety, it is just about impossible to shoot some one by accident. Also, most burglars know people keep guns by their beds; this is one of the first places they look when they break in. Most break-ins occur in the afternoon, because burglars know (from experience or talking to other criminals in prison) that is the least likely time find someone home. So they get the often unlocked and loaded gun from beside the bed first, to keep someone from using it lawfully in self-defense, if they come home unexpectedly, are in the basement, etc. If you make an effort to secure your firearms, where it will take time for someone to find (but you can still find/use in an emergency) you are vastly reducing the odds of it being used against you.
Another way people miss use statistics is to say any statistics that does not support their pre-conceived beliefs are false. It is a free county; if you want to do this, go ahead. But if you want act for your own and your family’s safety and best interest, it might be better to look at all the available facts, and then form your beliefs. The exact ratio of accidental/criminal vs. lawful shootings vary, but statistics and multiple studies done over the decades and around the county show the accidental/criminal ones are more prevalent then the lawful ones.
There are many times that a firearm was/could be used in home protection without being fired, or by being fired without death or nonfatal injury. They didn't count those did they?
This is another good point. But if you count the times a firearm was used in home protection without being fired or without hitting someone, you would also have to count this times idiots had a non-intentional discharge but didn’t hit any one. And you would have to count the number of times criminals stole a gun from a house, and got away with it with out shooting any one. These would be difficult to count (the reason the study cited did not count them) and I’m sure the ratio of bad to good shooting would change, but I’ve yet to see a study where it can be shown there are more good shooting then bad.
