I absolutely agree that you should know how to shoot and show responsibility. (I've comp shot for a long time)
I also think that any carry should be legal. I should have full advantage when it comes to my personal protection, don't take that away from me. I carry everywhere legal. I don't expect to get in a shootout, I don't want to. I always wear my seatbelt, I don't expect to get in a car crash, I don't want to. I just want it if, hopefully never, I need it.
However, if you open carry in today's time (around town) you are an idiot (law aside) as it would make you a target and comes with a plethora of different problems that it's not worth the hassle.
California has and always will have a population problem. Mass concealed carry might help with deterring crime, might help crime. I just don't want to live in a state that won't let me protect myself reasonably.
I would agree, far too many idiots who do not care about the law are the ones concealing and carrying right now in CA. Level the playing field and let those folks that can pass a stringent field test for handling, shooting and maintaining a gun get the CC. If you look back at all the worse mass shooting over the last few years, the one equalizer that could of been in place was not, another responsible person with a gun and ability to use it effectively.
