...assault weapons are quickly becoming the leading topic of America's gun control debate and will most likely remain the leading gun control issue for the near future. Such a shift will not only damage America's gun lobby, but
strengthen the handgun restriction lobby for the following reasons:
It will be a new topic in what has become to the press and public an "old" debate. Although handguns claim more than 20,000 lives a year, the issue of handgun restriction consistently remains a non-issue with the vast majority of legislators, the press, and public. The reasons for this vary: the power of the gun lobby; the tendency of both sides of the issue to resort to sloganeering and pre-packaged arguments when discussing the issue; the fact that until an individual is affected by handgun violence he or she is unlikely to work for handgun restrictions; the view that handgun violence is an "unsolvable" problem; the inability of the handgun restriction movement to organize itself into an effective electoral threat; and the fact that until someone famous is shot, or something truly horrible happens, handgun restriction is simply not viewed as a priority. Assault weapons—just like armor-piercing bullets, machine guns, and plastic firearms—are a new topic. The weapons' menacing looks, coupled with the public's confusion over fully automatic machine guns versus semi-automatic assault weapons—anything that looks like a machine gun is assumed to be a machine gun—can only increase the chance of public support for restrictions on these weapons. In addition, few people can envision a practical use for these weapons.
