Would anyone seriously want private citizens to be able to own nuclear weapons?
As VOR points out, the difference between arms and ordinance was established from the start. As the actual facts point out, semi automatic rifles are too expensive and difficult to conceal making them particularly unattractive in criminal activity. Statistics place their use at about 1-2 percent.
The reason semi automatic rifles are the focus of regulatory attacks here is that they are a less represented segment of firearm ownership compared to other weapons, making them easier to attack without as much unified defense in the firearm community.
For the full firearm banners -- the Brady crowd -- they represent a doable ban that can be accomplished today while working towards long-term goals.
For politicians, they can claim to do "something about crime" without actually dealing with the significant challenges that lead to violent inner city crime. Feel good, do nothing legislation even if a ban actually worked. 1-2 percent of the problem at best. None have the guts to attack the failed war on drugs, or segregation, or a lack of inner city economic development or failed education or -- most importantly for a politician -- failed responsibility among parents and the actual criminals. Blame the symptom, not the problem -- its safer.
The mainstream media in urban areas lacks diversity of background and opinion in the newsroom, regardless of their skin color. Urban and suburban middle to upper middle class from cradle to grave, Ivy league or the equivalent college experience, no life experience otherwise, typically little exposure to responsible firearm ownership, generally liberal views socially that include the 2nd Amendment (many of which I support, but not out of emotional bias and obviously not where the 2nd is concerned). Their coverage reflects this, though it's hard to tell the difference between basic ignorance and actual bias. It's likely a combo of both. The net result is a lack of even coverage.
Anti-2nd Amendment types are free to publicly claim that these rifles are machine guns. This even included a local politician that did a mailing where she implied though her images that a .50 rifle was a M2 .50 machine gun (a belt-fed M2 sitting in a pile of spent casings). The ILL Fraternal Order of Police (a political organization like most) being allowed to state: "police firearm deaths have eclipsed traffic deaths since the federal ban was lifted" while supporting a candidate (Duckworth) without providing any data linking those deaths to actual semi automatic rifles. During the same time crime has increased in general while pursuit tactics have worked to reduce traffic deaths -- no AWB link at all. And, nobody calls them on this. Chicago's "Top Cop" can go on televison and state "you can empty the magazine with one or two pulls of the trigger" and no one calls him on it. If you try, your letters to the editor just don't get published.
