With respect, I'm not sure all the facts support that conclusion.
To be clear, don't let's make this a gun control argument. This forum has enough of those.
But there's a large body of research to support De Becker's conclusion -- he doesn't ignore 'every single bit of research'. He merely ignores 'every single bit of research' that supports your opinion.
My take is simpler. I have yet to see any research on either side that wasn't conducted by somebody with an axe to grind. Most of the research that came out anti-gun was done by people out to prove that guns are dangerous. Most of the research that came out pro-gun was done as a reaction to the anti-gun research. To be fair, this is usually true of all controversial issues and probably human nature.
Yes, DeBecker's an extremist. But intelligent, well-educated extremists are a common (and often neccesary) part of how our society makes needed changes.
Even the NRA has to admit that our rights are in danger because too many idiots do stupid things with guns. DeBecker's radical wishes won't ever happen, but they may help to steer us in a direction to make more gun owners act more responsibly, and maybe discourage people from buying guns for the wrong reasons.
