I don't care for the way the article is written, but I'll concede the do have a tiny sliver of a point.
While I certainly don't think anyone should ever have to ask permission to carry a weapon, I would likewise expect that anyone who chooses to do so exercises their right responsibly.
As far as the antis' fears that EVERYONE will start carrying concealed (except for them, which is why they're scared in the first place, but that's besides the point), I can't logically conclude that is what will happen.
The probability of anyone who currently does not carry a weapon starting to do so on the 29th is slim at best. Simply being able to CCW does not a CCWer make.
The article cites the expense of the course and the certification. What it leaves out is the expense of a holster, clothing, mag holsters, etc... designed for concealment. Unless people start running around Mexican carrying, I don't think gun shops will be able to keep enough concealment holsters in stock.
Furthermore, CCW'ing is more than just strapping a gun on as with OC. Because the weapon is concealed, and because modes of carry can vary depending on your attire, it takes some getting used to. The first time I ever carried concealed I felt as though everyone's eyes were on my and I had a big sandwich board on pointing to my hip saying "GUN --->" So again: anyone who hasn't been doing this regularly is going to have a learning curve to follow.
The demographic I would most likely peg to take the best advantage of this new law are those gun owners who do not have a CCW permit and likewise do not enjoy the "attention" or what have you that goes with open carrying.
