Who will you shoot?

Editor,

I have one question for all those "gun enthusiasts" who claim they are willing to "lay down their lives" to protect the rest of us from the "peril" of "tyranny:"

How will you know when "tyranny" has visited itself on us? Who will you shoot to battle it? When will your shooting start?

I fail to see how one "patriot" with an AR-15 thinks he can defeat an armored division rolling into his town.
