The video clip below shows an illegal arms market in Pakistan, where firearms and ammunition are actually manufactured and then sold. Those who think that banning guns will work should keep in mind that the people in this gun market are able to produce machine guns and ammunition using technology that is quite primitive by American standards. Just imagine what more technologically sophisticated criminals in the United States could manufacture if they set their mind to it. Those who lack such an imagination can look to real examples from the United Kingdom, where criminals have produced machine guns .
