Ever hear the saying "When guns are outlawed only outlaws will have guns" ?
That is the exact situation a Mormon community finds itself in Mexico. Heavily armed drug gangs pull people out of their houses and put bullets in their heads while the Mormon community is told by the government it can not have weapons. This is the real world and not some rainbow and unicorn liberal paradise. Liberals think outlawing guns will result in a paradise. The exact opposite occurs.
A final point to consider while watching the video is that if we legalized drugs we would remove the funding source of the cartels. Classic reverse baptist and the bootlegger theory.
