In return for this generous gesture, I am expected to give an additional half-cent sales tax for each dollar spent every time I buy a bar of soap, underwear or a new pair of shoe inserts. Thanks, but no thanks. Leave my property tax alone and leave my half-cent sales tax in my pocket. There are a few problems with this line of thinking. The responsibility of safe gun handling and ownership is not the firearms, the manufacturers or the safety devices.
Responsibility is a human characteristic.
Safety has to be part of the person, not the tool. You can't buy it and you can't make it. The Chinese have gotten into the trigger lock market. These are truly works of art. I have seen them pop off with a screwdriver.
