I'm going to go out on a limb and be a dissenting opinion.
Having read the article posted, I don't necessarily DISAGREE with the overall statement that there is some necessity for clarification as to who can legaly own a firearm. Do we not keep hounding on the fact that mentally unstable people keep buying firearms and shooting up movie theaters, schools, and malls, since thier records are not properly documented therefore disqualifying them from gun purchases? You can't have it both ways, total deregulation but restrictions on dangerous people getting firearms too. They are law abiding, up to the point they are triggered. Freedom of speach is also regulated, that's why we have slander laws. Should the restrictions be as sweeping? no.
The latter half of the article advocates the requirement for some level of training for a CCW. Definately agree with that, sorry. The most dangerous firearm out there is the one the owner doesn't know how to use. Buying a pistol for "home defense" that is going to sit on the top shelf until its rusted together isn't going to protect anybody. I would go so far as to say it's more dangerous for the owner, as they probably haven't practiced with it enough to be able to HIT anything (not that most of the police officers now do that much better, but that's another thread) without injuring themselves or an innocent bystander. My wife's aunt has a CCW for life in CA and I wouldn't want to be anywhere NEAR her if she actually had to use it, and she's been trained (medically retired prison guard). Every couple years she has to "requal" with her pistol. It boils down to less than a magazine, usually two-three shots, SOMEWHERE on a target at 10 yards. She's on so many medications (including but not limited to marijuana and oxycodone) she can barely pull the trigger more than that.
