Some people put their lives on the line every day to protect everyone's freedom. The military (soldiers, sailors, Marines, airmen, coast guard, police, firemen, etc.) risk their lives and their families peace so that we can go about our daily lives in relative comfort.
I respect his sacrifice. I'd rather not have any of our public servants lose their lives. But having been in the military, I know that there will be more lives lost keeping this nation's freedom.
Freedom is never free. Those who think it is, have never served and, in many if not most occasions, look down on those that have. I pity those people.
To quote Nathan Hale, "I regret that I have but one life to give for my country."
