He does not bear the gun in vain:

I have some friends who are police officers. All of them carry guns. I was recently at a local government hearing where one of my law-enforcement buddies was the official security. He had on his uniform, badge, and patches that identified him as an officer of the law. He carried a gun. As I sit here thinking I cannot recall that any of the officers of the law with whom I am acquainted have ever shot anyone. I didn't observe that anyone at the public hearing, I mentioned, who looked like my friend's gun made them nervous. Thankfully, in the community where I live the reality of Romans 13:4--"He bears not the sword in vain"--is not a reason for law-abiding folk to be afraid. In fact my friend's presence brought security.In recent news the question has been raised about whether an Army officer, who went rogue, should have been able to purchase a gun. Perhaps the more significant question is, "What is wrong with a culture that produces an officer sworn to protect his nation who cannot be trusted?" It could be you and I have a part in that.

It's STTA.
