Again, you statement shows you don't understand the self defense laws, and
qualifications for the license.

That depends on the jurisdiction. In places like the UK, he's pretty much on
the mark. Not every jurisdiction allows you to draw and shoot every time you
feel threatened.

Having a license and carrying a legal
concealed weapon does not give you the right to use the weapon unless you
have no other choice. You are still responsable for taking any and all
reasonable avoidance options.

So the actual probability of being in a situation where you can legally use it
is extraordinarily low.

One reason why professional criminals don't routinely carry guns is that they
don't usually need them and they can get in trouble if someone finds that they
have one.
