Here we see Dennis Henigan of the Brady Campaign misquoting the 2nd Amendment, leaving out "the people".
The actual second amendment is:
"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."
What Henigan says is:
"The second amendment is the only provision in our Bill of Rights that actually states its own purpose. It says a well regulated militia being necessary to the security of a free state, the right to keep and bear arms shall not be infringed."
