The American problem isnt in its gun policies, it is in its culture. Kids get to learn about their history of countless Wars, their father went to Vietnam and their grandpa went to WW2 and Korea. They have this thing called ''the terror meter'' wich is broadcasted largely to tell the people what is the scale of the terrorism threat, they are flooded by medias dedicated to control the crowd (see the movie, ''the longest night'' about McArthy's media reform) abusive consumerism, and crazy competition as a result of a capitalistic government. If you have pimples you are ugly, if you are fat you wont get laid, if you dont smell like flowers people wont talk to you, if you wear old clothes you wont make any friends, 60% of murderers are close friends with their victims... violence is completely normalised, the army comes in schools to speak about war, they build a mosque on ground zero... bla bla, all theese contradictions that form the american paradox.
A culture of Fear + fascist propaghanda + religious based war + lots of guns = a whole bunch of dead people.
there was a saying in the Canadian army during the WW2: When british saw germans, they shot, when germans saw british they shot, when we saw americans, everybody ran for it.
