I really feel sorry for the individual troopers on those lines. Let's see, you're 19 years old, you've been working down at the pharmacy or going to college, and get called up to protect the inauguration. You've been sleeping on the cold hard marble floors for two weeks.
They give you your M4 and LIVE AMMO to use against YOUR OWN CITIZENS.
I've got to wonder how many will balk at the orders to fire? How many will bolt from their lines? How many will fire on their their own countrymen? Either way, it could potentially be a bloodbath the will make Kent State look like a paper cut.
