Absolutely not true at all.
The instance of violence and gun violence has far more to do with the varying levels of income in a society than any other factor, whatsoever.
If everyone in the country owned a gun and was middle income, there will be a low amount of violence, including gun violence.
If everyone was rich in a country, and owned a gun, there will also be a low amount of violence, including gun violence.
And if everyone in a country is poor, and owned guns, there would still be a low amount of violence, and gun violence.
It does not freaking MATTER how many people have weapons. EVERYONE has access to weapons.. I can make a Taser out of a disposable camera and a paper clip, for crying out loud.. I have heard of people getting stabbed with a screwdriver. People get SMOTHERED to death with pillows, or bludgeoned with (most recently in my neighborhood) a table leg, or baseball bat, hammer- name your blunt instrument.
We don't need guns to cause violence or deaths.. Guns just expedite the process of killing someone, and cause less bloodshed and effort, so that a person can make a kill with very little effort.
Again, GUNS do not kill people- People kill people.
*Cough* Somalia *cough* Sudan *cough* Chad *Cough* Zimbabwe.
I think you didn't actually mean that...
*cough* Panga *cough* Machete *cough cough*.
Citing events in Africa pretty much proves the point that culture has much mroe to do with violence than the presence or absence of guns.
*Cough* That was after they used the guns.
The same could have been said for Afghanistan, parts of the Phillipines Central America in the 80's etc. It's not a cultural thing as such because under the same conditions with a lack of law, and profusion of firearms this kind of crap happens globally.
