If CA approved concealed carry permits or I moved to TX or AZ, I would carry without hesitation. Of course, stringent training and testing should be required and you should have to be squeaky clean to get the permit. Sure crazies will get through the cracks, but they’ll find a black market to obtain guns anyway. Outlawing firearms just doesn’t work – just look at the drug war as a comparison.
Criminals will always have guns – I just want a level playing field.
