Because I can’t carry a cop.
Melvin starts his question on a false premise. Cops are NOT responsible for protecting the public. This question has been settled in a court of law.
Nor does your gun receive a salary, benefits and a pension, take sick days or take donut breaks, let alone have other calls to respond to while you're in trouble. In fact, you can buy a very nice gun made for concealed carry, plus a holster or two and a bunch of ammo for the weekly paycheck of a single cop.
No knock on (most) cops, but they simple cannot be everywhere at once (and I wouldn't want to be living in a society where anything close to that was the case).
These anti-gun libs have their heads up their rear ends (or just haven't had the misfortune of being mugged, etc. - which I certainly do NOT wish upon them or anyone else).
