Here is great post on Larry Correia's blog about why there shouldn't be any new gun control and why lots of the restrictions we have should be rolled back.
It is a long, but very worthwhile read. Great facts and references for lots of the items you are likely to encounter from those who are on the fence gun-rights wise.
I know Larry peripherally from another forum we are both members of, and have chatted with him online about 10mm handguns. He has an custom STI 10mm FYI.
You can check out his thoughts here (http://larrycorreia.wordpress.com/2012/12/20/an-opinion-on-gun-control/).
Very good article, read it the other day. Interesting guy besides his Monster Hunter series of scifi books.
Sadly, logic and fact do little when the other side's argument is pure emotion mixed with fear. Like most of us know, this isn't just about guns.
This will do little for the hard-core anti-gun crowd. But committing this type of information to memory is great during times like this when fence sitters engage us in questions about proposed legislation.
You might be interested in Dr Faria's article. His articles appear in various medical journals and as such, are footnoted etc. Retired local surgeon with an interesting background.
