dakatl and all...
I'll be honest, there is convincing evidence that UBC, registration, etc actually does decrease gun crime, violent crime fatalities, and suicides. It's not conclusive by any means, but it's arguable at least. I think it's a disservice to our side of the debate to not admit that the other side has some acceptable basis for their points.
I just don't think those relatively small statistical improvements to safety outweigh the importance of the purpose of the 2nd amendment.
Let me be clear on what I think that purpose is also... I don't think it means that we have the ability to overthrow the government. It just means that individuals have the ability to get the ability to overthrow the government. We don't get tanks and canons and whatnot. We do get the tools necessary to procure some tanks and whatnot if it came to that. Generally, we have the tools necessary for a SHTF type situation, whatever the cause may be. We are not 100% dependent and at the mercy of the government. (maybe 80-90% but definitely not 100%, lol)
Actually, there is little to no correlation between 'gun crimes' committed in a state and how 'strict' the laws are.
I would suggest going through the site below since I'm sure you are getting this information from some of the studies this criminologist pokes holes in.

A common sense question will give you the answer though. What is the safest state in the US, and what are it's gun laws?
Year after year that state is Vermont, and until a few years ago, they literally had NO state gun laws unless they were required by the feds. Today the only laws they have are a 15 round mag limit of I remember correctly.
