Why is this Marine a threat to public safety?

“I am a Commissioned Officer currently serving on Active Duty in the United States Marine Corps. I have deployed five times in support of Operation Iraqi Freedom. I have been granted a Top Secret security clearance three times during my career after thorough background investigations (and polygraph tests) by various Federal agencies. I have never in my life been treated for any type of psychological disorder.

“I am also the owner of several firearms; I own two "assault" rifles, a shotgun, and three handguns. Each of these weapons is secured by a trigger lock and stored in a locked safe. I have a concealed weapons permit in my home state; a permit granted to me after demonstrating weapons competence to a state-certified instructor and a comprehensive background check by the State Police. I have never in my life violated any firearms-related law.”

(Well, Sir, you answered the question with the opening of your second paragraph. You own guns. Like you, I was granted a Top Secret clearance. I was trusted with the lives of soldiers, both in peacetime and in war. And, like you, as the owner of several rifles and shotguns and one revolver, I am, according to some Americans, a threat to public safety.

(In reality, you and I are threats only to those who would threaten us and our families and other citizens. We would even protect those who disagree with us, using whatever means necessary.

(That is a difference between us and them. We know they have a right to opinion. They, however, think all should believe as they believe. That is not the America whose Constitution you and I and millions of others swore to uphold and defend.)
