I'm going to out myself here, please don't be too hard on me, as I was pretty uninformed about gun laws a couple years ago, and only had a passing familiarity with firearms (the only guns we had were ones that have been in the family for a few generations). My own political leanings fall somewhere in between libertarian and anarchist and I usually support democratic causes, so I'm ashamed I admit that I was one of the people who voted to approve 594. This was solely because I didn't look too far into it and believed most of what I was heading in the news about the then-proposed law. I wasn't anti-gun, just in favor of "common sense".
Until I actually went into a gun store and talked with the owner about the process for buying a gun I didn't know that background checks were already required on all new gun purchases, that there was no "gun show loophole", and that what we actually need is better enforcement of the existing gun laws,not new redundant and ineffectual legislation.
BlackRyder, before the referendum was held, I talked to an employee of Cabelas that sold me a pistol about this issue. This employee told me that I-594 was a "good" thing, and probably considered himself to be a "constitutional patriot". I can forgive someone for being mistaken, but not when they work in a gun shop and should know better. I don't plan to buy any more guns, but if I do, I will buy it elsewhere and then send a letter to Cabelas telling them that I am boycotting them over this employee's statements to me.
