Well I have to admit, I'm glad this isn't some flame war back and forth. But I believe you misinterpret me and believe me for some zealot, nor do I even consider myself a conservative.
These are all besides the point, I'm just pointing out little tidbits - not trying to argue for or against any true stance.
Come to think of it, the Armed Citizen isn't a secondary source because it compiles secondary sources (typically local newspaper, news reports, etc). I definitely don't depend on objectivity anywhere in this world, everything always has spin.
As for your queries on better data, I'd have to ask where? "Instant Justice"? Best numbers I would even think of attempting to investigate would be ratio of armed burglaries/entries/etc to the number of home shootings (which could be wildly varied depending on viewpoints and situations).
Personally, I grew up in a home where my father kept a loaded 12ga in his closet, which thankfully never had to get brought out. We were taught to not ever touch it, but to know where it was and how it operated. This situation isn't always a good idea for some, depending on age/responsibility/comfort of others in the home. Maintaining a loaded firearm in a home can be an extreme hazard depending on the environment. There are far too many accidental discharges in this country (any is far too many). Honestly many people would likely do better with a baseball bat and a can of hornet spray by their bedside if they don't take the time to be proficient and safe with a firearm. I don't think it's an unrealistic view for one to be maintained in a home for home defense. I've lived in a major city that has significant crime (top 5 for violent crime) for five years, and opted not to get a concealed carry permit because I didn't see a need for it and have always considered myself fairly street-smart.
I don't see you as some anti-gun guy, I also don't think either of us has an unrealistic view of how guns can be used. Just a difference of opinions. I'm going to stop rambling now.
