This is the truth about the CDC....

In June the House Appropriations Committee adopted Dickey's amendment, which included a prohibition on the use of CDC funds "to advocate or promote gun control," and in July the full House rejected an attempt to restore the money.
What was the CDC doing with their money.....
Contrary to this picture of dispassionate scientists under assault by the Neanderthal NRA and its know-nothing allies in Congress, serious scholars have been criticizing the CDC's "public health" approach to gun research for years. In a presentation at the American Society of Criminology's 1994 meeting, for example, University of Illinois sociologist David Bordua and epidemiologist David Cowan called the public health literature on guns "advocacy based on political beliefs rather than scientific fact." Bordua and Cowan noted that The New England Journal of Medicine and theJournal of the American Medical Association, the main outlets for CDC-funded studies of firearms, are consistent supporters of strict gun control. They found that "reports with findings not supporting the position of the journal are rarely cited," "little is cited from the criminological or sociological field," and the articles that are cited "are almost always by medical or public health researchers."
Further, Bordua and Cowan said, "assumptions are presented as fact: that there is a causal association between gun ownership and the risk of violence, that this association is consistent across all demographic categories, and that additional legislation will reduce the prevalence of firearms and consequently reduce the incidence of violence." They concluded that "ncestuous and selective literature citations may be acceptable for political tracts, but they introduce an artificial bias into scientific publications. Stating as fact associations which may be demonstrably false is not just unscientific, it is unprincipled." In a 1994 presentation to the Western Economics Association,State University of New York at Buffalo criminologist Lawrence Southwick compared public health firearm studies to popular articles produced by the gun lobby: "Generally the level of analysis done on each side is of a low quality. The papers published in the medical literature (which are uniformly anti-gun) are particularly poor science."
Ironic that something that fallaciously calls itself "reason.com" is little more than a purveyor of red meat emotionalism to gun fetishists like yourself.
But your gullibility is not the issue here.
The question was why the CDC didn't have those statistics and the answer is because gun fetishists obstructed the legitimate collation of statistical firearm injury and deaths data because that exposes the rampant harm that guns are causing to society.
Once these facts become public knowledge there will be a growing incentive towards ensuring that gun owners are held accountable for their firearms and the damage they are doing.
Your kneejerk reaction will be to claim that is already happening but the OP proves that it isn't.
That is your problem and trying to censor the CDC is no longer an option for you.
