>>I have been searching for some time on statistical information concerning legally owned firearms and their use in crime. <<
I'm pretty sure the actual statistics don't exist, at least not where the average person can get to them. However, a lot of info can be found at
http://www.keepandbeararms.com/ . This site is dedicated to collecting the largest collection of self-protection and pro-gun news articles possible. Just a casual review of their collection proves that legally owned firearms have a BIG impact on crime.
I'm a paying member there (check my bio..) and I've thru their data time and time again but havn't found anything that would be usefull, just conjecture and personal accounts.
I think by its very omision from databases the information must be very incriminating to the anti-gun loby.
