I don’t get the logic in your post: How many people pack heat before going to church? I don’t think very many, if any at all.
Unless it's open carry, you're not going to know if someone can fight back unless they are forbidden by law.
If a church (or any other place for that matter) doesn't prohibit people from being able to defend themselves i.e. a Gun-Free zone, then the bad guys won't know if they will come up against someone who can fight back.
Declaring an area a Gun-free zone virtually guarantees only the reprobates will be armed.

I think more people carry in church than you might realize.
