The only kind of weapon I can see reason for to have..
Is a 9mm pistol in the nightstand next to your bed for safety if something should happen at home. (Home invasion or something alike)
Nope, there's no good reason for that either. The data shows that's much more dangerous for you and your family than NOT having that same handgun on the nightstand.

You keep posting this gun control propaganda image over and over again (presumably hoping that if you repeat it enough times, people will somehow overlook the fact that while it claims statistics in support of your beliefs, it does not cite the source(s) for them).
Let me instead cite another source which tells a different message:
https://archive.org/details/MoreGunsLessCrimeIn his book, "More Guns, Less Crime," John R. Lott (a former professor of law and economics who has held positions at a number of distinguished universities in the US including Yale, Stanford, UCLA and Wharton) uses statistics collected by the FBI to show that within the US, the more guns in the hands of the people in any region, the lower the crime rate. Interestingly, the book was originally commissioned by a gun control group (Handgun Control) under the assumption that his conclusion would be the opposite of what he in found.
I'm sure most of you who disagree with this message will ignore the book and continue to cling to whatever evidence you can find to support your own emotionally derived beliefs. For those of you who are American, crouch down and lick the hand that feeds you. May your chains set lightly upon you and may posterity forget that you were our countrymen.
