Question: Who was responsible for the massacre that led to suzanna hupp's book "From Luby’s to the Legislature: One Woman’s Fight Against Gun Control"?

<P0-S0> In United States politics, the Dickey Amendment is a provision first inserted as a rider into the 1996 federal government omnibus spending bill which mandated that "none of the funds made available for injury prevention and control at the Centers for Disease Control and Prevention (CDC) may be used to advocate or promote gun control." <P0-S1>  In the same spending bill, Congress earmarked $2.6 million from the CDC's budget, the exact amount that had previously been allocated to the agency for firearms research the previous year, for traumatic brain injury-related research. <P0-S2>  The amendment is named after its author Jay Dickey, a Republican member of the United States House of Representatives from Arkansas. <P0-S3>  The amendment was introduced after lobbying by the National Rifle Association in response to their perceived bias in a 1993 study by Arthur Kellermann that found that guns in the home were associated with an increased risk of homicide in the home, as well as other CDC funded studies and efforts. <P0-S4>  Mark L. Rosenberg, the former director of the National Center for Injury Prevention and Control, has described this amendment as "a shot fired across the bow" at CDC researchers who wanted to research gun violence. <P0-S5>  Many commentators have described this amendment as a "ban" on gun violence research by the CDC. <P0-S6>  In a 2012 op-ed, Dickey and Rosenberg argued that the CDC should be able to research gun violence, and Dickey has since said that he regrets his role in stopping the CDC from researching gun violence, saying he simply didn't want to "let any of those dollars go to gun control advocacy." <SEP> <P1-S0> Suzanna Gratia Hupp, DC (born September 28, 1959), is a former Republican member of the Texas House of Representatives, who represented traditionally Democratic District 54 (Bell, Burnet, and Lampasas counties) for ten years from 1997–2007. <P1-S1>  After surviving the Luby's shooting in 1991, Hupp became a leading advocate of an individual's right to carry a concealed weapon. <P1-S2>  Hupp was elected to her first of five consecutive terms in 1996. <P1-S3>  She did not seek a sixth two-year term in 2006. <P1-S4>  She has also written a book called "From Luby’s to the Legislature: One Woman’s Fight Against Gun Control", published by Privateer Publications, San Antonio, Texas. <SEP> <P2-S0> Stephen P. Halbrook is a Senior Fellow at the Independent Institute and an author and lawyer known for his litigation on behalf of the National Rifle Association. <P2-S1>  He has written extensively about the original meanings of the Second Amendment and the Fourteenth Amendment (the latter as applied to Second Amendment rights). <P2-S2>  He has argued and won three cases before the US Supreme Court: "Printz v. United States", "United States v. Thompson-Center Arms Company", and "Castillo v. United States". <P2-S3>  He has also written briefs in many other cases, including the Supreme Court cases "Small v. United States" (pertaining to the Gun Control Act of 1968) and "McDonald v. Chicago". <P2-S4>  In "District of Columbia v. Heller", he wrote a brief on behalf of the majority of both houses of Congress. <P2-S5>  More broadly, his decades of research on the Second Amendment contributed to the intellectual foundation of the "Heller" decision. <P2-S6>  He has written many books and articles on the topic of gun control, some of which have been cited in Supreme Court opinions ("Heller", "McDonald", "Printz v. United States"). <P2-S7>  He has testified before congress on multiple occasions. <P2-S8>  Halbrook’s most important scholarly contribution, however, was the book "That Every Man Be Armed", originally published in 1986. <P2-S9>  The book was the most thorough analysis of the legal history and original intent of the Second Amendment. <SEP> <P3-S0> The Luby's shooting, also known as the Luby's massacre, was a mass shooting that took place on October 16, 1991, at a Luby's restaurant in Killeen, Texas, United States. <P3-S1>  The perpetrator, George Hennard, drove his pickup truck through the front window of the restaurant, and immediately shot and killed 23 people, and wounded 27 others before fatally shooting himself. <P3-S2>  It is the fourth deadliest massacre by a single shooter in U.S. history.
