I searched, thought somebody would have posted this already. Washington Post ran a
featureon Sunday based on Pew Research polling data. The results, IMO, reflect a lack of understanding in the general public. Some results - 85% of respondents favor background checks on private sales, 70% (!) support a Federal sales database for tracking, 57% support an "assault weapons" ban. I don't know much about them, but I consider Pew research more trustworthy than the Bloomburg Center at Johns Hopkins.
Obviously, people in general don't understand the NICS system, or the fact that registration always leads to confiscation eventually. ATF can run traces in 24 hours in the vast majority of cases, so the value of any new database system is highly suspect. Also, the fact that ALL rifles add up to something like 3% of homicides shows that there is no rational basis for any kind of rifle ban. Furthermore, how many people know that the last three years have seen the lowest homicide rates in the last half-century? For most Americans alive today, the homicide rate has never been lower than it has been the last three years.
Gun rights supporters face an uphill battle due to popular ignorance on the subject, reinforced by the media. Only a few years ago, I didn't know better myself, and believed in the "gunshow loophole" because it was so widely accepted in the media and politicians. I know better, now, of course, but for people with no exposure to the shooting sports & hobbies, that ignorance is harmful to those who enjoy firearms. I would love to see a public survey like the Pew poll, but with better framing. Let people know that homicides have been in steady decline for 20 years and are near 50-year lows, that rifles are almost never used in homicides, and see what the poll results would be then. Remember, knowing is half the battle!
