Question: Richard Labunski, a journalism professor at the University of Kentucky and newspaper columnist who is notable for being an outspoken advocate for reforming the United States Constitution in his book "The Second Constitutional Convention", wrote about the United States Bill of Rights, which are the first of how many amendments to the United States Constitution?
Context: George Mason (sometimes referred to as George Mason IV; December 11, 1725 [O.S. November 30, 1725] October 7, 1792) was a Virginia planter and politician, and a delegate to the U.S. Constitutional Convention of 1787, one of three delegates who refused to sign the constitution.  His writings have been a significant influence on political thought and events, including substantial portions of the Fairfax Resolves of 1774, the Virginia Declaration of Rights of 1776, and his "Objections to this Constitution of Government" (1787) in opposition to ratification of the constitution.  The Virginia Declaration of Rights, which Mason principally authored, served as a basis for the United States Bill of Rights, of which he has been deemed the father. The Constitution of Palau, Constitution of the Republic of Palau was adopted by the Palau Constitutional Convention from January 28 to April 2, 1979, ratified at the Third Constitution Referendum on July 9, 1980, and entered into force January 1, 1981.  The Second Constitutional Convention certifies the proposed amendments to the Constitution of the Republic of Palau that were duly adopted by majority vote of the Delegates on July 15, 2005. The Congressional Apportionment Amendment (originally titled Article the First) is a proposed amendment to the United States Constitution, one of twelve proposed amendments to the United States Constitution approved by the 1st Congress on September 25, 1789, and sent to the legislatures of the several states for ratification.  If adopted, it would establish a formula for determining the appropriate size of the House of Representatives following each constitutionally mandated decennial census.  It is the only one of the twelve that has not been adopted, as it has not been ratified by enough states for it to become part of the Constitution.  Ten of the proposed amendments (numbers 3 through 12) were adopted in 1791, becoming the First through Tenth Amendments to the Constitution, and collectively known as the Bill of Rights.  The second of the twelve proposed amendments was adopted in 1992, becoming the Twenty-seventh Amendment. The National Monument to the U.S. Constitution (also known as the Constitution Bicentennial Monument) is a monument commissioned of Australian artist Brett-Livingstone Strong by Warren E. Burger, Chairman of the Commission on the Bicentennial of the United States Constitution, to commemorate the 200th anniversary of the signing of the United States Constitution.  One of a pair created by Strong to commemorate historic anniversaries, along with The United States Presidency Monument, it was dedicated by President Ronald Reagan at Independence Hall in Philadelphia on September 17, 1987.  Both monuments are the property of the Global EventMakers,Inc., a Florida-based company with principal offices in Richmond, Virginia.  The monument has been transported for display at several public events around the country and was scheduled to begin a twenty-city traveling exhibit as part of the Spirit of Freedom Tour beginning in September 2009.  Due to poor economic conditions, The Tour never commenced; however the Monuments accompanying original replicas of the United States Constitution and Bill of Rights are being produced for placement in America's schools.  All rights to the Constitution Monument and the Original Replicas of the Constitution were transferred to The American Constitution Spirit Foundation, a Virginia non-profit, in March 2010.  The Foundation plans to find a permanent home for the monument during 2013. The Revolutionary People’s Constitutional Convention (RPCC) was a conference organized by the Black Panther Party (BPP) that was held in Philadelphia from September 4–7, 1970.  The goal of the Convention was to draft a new version of the United States Constitution and to unify factions of the radical left in the United States.  The RPCC represented one of the largest gatherings of radical activists across movements and issues in the United States.  The Convention was attended by a variety of organizations from the Black Power Movement, Asian American Movement, Chicano Movement, American Indian Movement, Anti-war movement, Women’s Liberation, and Gay Liberation movements.  Estimates of attendance range from 6,000 to 15,000.  Attendees convened in workshops to draft declarations of demands related to various issues, which were ultimately intended to be incorporated into a new constitution which would function as the final vision of those movements.  The RPCC also signified a shift in BPP focus from black self-defense to a broader revolutionary agenda.  While conflicts did arise during the Philadelphia Convention, the conference was ultimately deemed a success by the Panthers.  After the Philadelphia conference attempts were made to reconvene to finalize and ratify the new constitution in Washington, DC a few months later, but ultimately failed due to police interference and Panther disorganization. A More Perfect Constitution is a book published by American political scientist at the University of Virginia, Larry J. Sabato, in which he proposes a constitutional convention to substantially overhaul the United States Constitution.  He points out that after the Bill of Rights, there have only been seventeen constitutional amendments over the past 220 years.  He argues that a constitutional convention is overdue and is something that the Founding Fathers would have wanted.  He offers 23 proposals for revising the Constitution. The Bill of Rights is the first ten amendments to the United States Constitution.  Proposed following the oftentimes bitter 1787–88 battle over ratification of the U.S. Constitution, and crafted to address the objections raised by Anti-Federalists, the Bill of Rights amendments add to the Constitution specific guarantees of personal freedoms and rights, clear limitations on the government's power in judicial and other proceedings, and explicit declarations that all powers not specifically delegated to Congress by the Constitution are reserved for the states or the people.  The concepts codified in these amendments are built upon those found in several earlier documents, including the Virginia Declaration of Rights and the English Bill of Rights 1689, along with earlier documents such as Magna Carta (1215).  In practice, the amendments had little impact on judgements by the courts for the first 150 years after ratification. Sanford Victor Levinson (born June 17, 1941) is an American legal scholar, best known for his writings on constitutional law and as a professor at the University of Texas Law School.  He is notable for his criticism of the United States Constitution as well as excessive presidential power and has been widely quoted on such topics as the Second Amendment, gay marriage, nominations to the Supreme Court, and other legal issues.  He has called for a Second Constitutional Convention of the United States. A More Perfect Union: America Becomes a Nation is a 1989 American feature film dramatizing the events of the Constitutional Convention.  The film was produced by Brigham Young University to commemorate the 200th anniversary of the drafting of the United States Constitution, and many professors from BYU's School of Fine Arts and Communications were involved in its production either as actors or in other capacities.  After its release, the film was officially recognized by the Commission on the Bicentennial of the United States Constitution as "of exceptional merit". Richard Labunski is a journalism professor at the University of Kentucky and newspaper columnist who is notable for being an outspoken advocate for reforming the United States Constitution in his book "The Second Constitutional Convention".  He has been a prominent critic of voter apathy, low voter turnout, and excessive campaign spending.  Labunski's critically acclaimed "James Madison and the Struggle for the Bill of Rights" (2006) argued that Madison was initially lukewarm to the idea of a Bill of Rights to the Constitution, but later came to energetically support the ten amendments and worked hard for their inclusion.  He has called for a Second Constitutional Convention of the United States, and argued that reform will not happen through the current system because Congress would be reluctant to "limit its own powers."
