From the New York Times Opinion Pages. Fanfare for the Comma Man.
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.
"There are three commas. The one after “state” would be used today; the one after “arms” would not; the one after “militia” is ambiguous; and all three have caused a world of hurt, confusion and argumentation over the last 223 years."
