Gun laws in the United States of America are one of the most controversial and poorly-understood parts of the legal system. There are Federal rules, state rules, and then there's the much-misquoted Second Amendment. Some states allow concealed carry permits, while others do not. Some permit the ownership of high capacity magazines and automatic or semi-automatic weapons, while others do not.
Ronald Reagan laid the groundwork for the 1994 assault weapons ban which since expired, with a proliferation of such weapons has resulted, with a gridlocked Congress seemingly unable to figure out what it wants to do next.
America's guns are owned by about a quarter to a third of its population, with 3% of Americans owning 50% of the guns. Most of these gun owners agree with non-gun owners that sensible regulation of the type commented on in the Second Amendment - which Justice Antonin Scalia would regularly note, frames gun rights in the context of "a well-regulated militia" - is probably a good idea.
But in order for any consensus to be reached about what the rules should be, it's first important for people in the conversation to be pretty darn sure what the rules currently are! Let's find out how you fare on that complex subject.
