Kopel opposes gun control and is a benefactor member of the National Rifle Association of America. His articles on gun control and gun violence have been cited in the Opposing Viewpoints Series.[9] In 2003, Kopel wrote in National Review "Simply put, if not for gun control, Hitler would not have been able to murder 21 million people."[10] In 2008 he contributed an article to the 59th Volume of the Syracuse Law Review entitled "The Natural Right of Self-Defense: Heller's Lesson for the World."[11] He appeared in FahrenHYPE 9/11, a film that disputes the allegations in Fahrenheit 9/11. Kopel's Independence Institute received 1.42 million dollars of funding for its activities by the National Rifle Association.[12][13]
While professing to be an opponent of gun control, Kopel testified before a U.S. Senate Judiciary Committee on March 26, 2019, that he in fact supports "Red Flag Laws" aka Extreme Risk Protection Orders, that are heavily supported and pushed by gun control groups and advocates.[14]
In 2008, Kopel appeared before the United States Supreme Court as part of the team presenting the plaintiff's oral argument in District of Columbia v. Heller. His Heller amicus brief for a law coalition of law enforcement organizations and district attorneys was cited four times in the Court’s Heller opinions. His brief in McDonald v. Chicago (2010) was cited by Justice Alito’s plurality opinion, and twice by Justice Stevens’ dissent. He has also testified numerous times before Congress and state legislatures, including before the U.S. Senate Judiciary Committee on the Supreme Court nominations of Elena Kagan and Sonia Sotomayor.[15]
Kopel testified on January 30, 2013, six weeks after the Newtown, Connecticut, Sandy Hook Elementary School shooting, before the Senate Judiciary Committee on gun violence.[16] One month later MSNBC.com revealed that Kopel and the Independence Institute had received $108,000 in grants from the National Rifle Association's Civil Rights Defense Fund, and that another witness at the Senate Judiciary hearing, David T. Hardy, testifying as a private attorney in Tucson, Arizona, had received $67,500 in grants from the same NRA Civil Rights Defense Fund in 2011.[17]
The Fox News affiliate station in Denver, Fox31, and correspondent Eli Stokols in May 2013 revealed that Kopel had received $1.39 million in grant money from the NRA Civil Rights Defense Fund between 2004 and 2011. Fox31 reported Kopel's NRA funding after the Colorado-based Independence Institute filed suit in Colorado challenging the state's gun laws with Kopel as the lead attorney.[19]
The New York Times changed Kopel's author ID for the online opinion piece, "Bloomberg’s Gun Control That Goes Too Far for the Average Citizen," on April 18, 2014, to reveal that that Independence Institute, where Kopel is research director, has "received grant money from the National Rifle Association's Civil Rights Defense Fund."[13] On April 24, 2014, The Progressive reported that Kopel and his Independence Institute "have received over $1.42 million including about $175,000 a year over eight years from the NRA."[20]
