In the USA supermarkets I saw guns for sale for as little as $25. In a country that has NO guns on open display, I felt much safer (Canada, UK, for example).

60 Minutes asked expert Joe Vince, a former top official at the Bureau of Alcohol, Tobacco and Firearms, if anyone, even a terrorist, could easily buy 50-caliber rifles.

"We are the candy store for guns in the world. And it's easy for people to acquire them here," says Vince, who adds that America is "absolutely" the best place for a terrorist to equip himself with guns.

Black market or legally bought, if guns are taboo then surely it stands to reason that there will be fewer deaths attributed to bullets.
