The wording of the Second Amendment to the Constitution came under renewed scrutiny as Vice President Joe Biden led the White House task force on guns.
The Second Amendment says: "A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed."
Merriam-Webster's Collegiate Dictionary offers three definitions of militia:
: a part of the organized armed forces of a country liable to call only in emergency
: a body of citizens organized for military service
: the whole body of able-bodied male citizens declared by law as being subject to call to military service
In interpreting the Constitution, opponents of gun control tend to support a definition like the middle one, which doesn't refer to a legal army; supporters of gun control generally support the other two.
