Ok, I did. Was this the section you’re pointing out?
”There are many legal and responsible uses for guns; an individual’s right to own and possess guns was established in the U.S. Constitution and affirmed in the 2008 and 2010 Supreme Court rulings in District of Columbia v. Heller15 and McDonald v. City of Chicago.16 However, the scarcity of research on firearm-related violence limits policy makers’ ability to propose evidence-based policies that reduce injuries and deaths and maximize safety while recognizing Second Amendment rights. Since the 1960s, a number of state and federal laws and regulations have been enacted that restrict government’s ability to collect and share information about gun sales, ownership, and possession, which has limited data collection and collation relevant to firearm violence prevention research. Among these are the amendments to the Gun Control Act of 1968,17 which prohibits the federal government from establishing an electronic database of the names of gun purchasers and requires gun dealers to conduct annual inventories of their firearms.
In addition to the restrictions on certain kinds of data collection, congressional action in 1996 effectively halted all firearm-related injury research at the CDC by prohibiting the use of federal funding “to advocate or promote gun control.”18 In 2011, Congress enacted similar restrictions affecting the entire U.S. Department of Health and Human Services.19 The net result was an overall reduction in firearm violence research (Kellermann and Rivara, 2013). As a result, the past 20 years have witnessed diminished progress in understanding the causes and effects of firearm violence.“
