I've seen one, maybe 10 years ago. It was the contractor in Iraq. That's enough for me. I don't need to witness the barbarity of these monsters to know what they did to the guy. I grieve for the victims and their families. I have family members in grave danger because of their work with Syrian refugees in the Middle East as we speak.
I respect Don's service to this country and he has certainly earned the right to express his opinion, though all Americans have that right. I'll gladly watch a video of Isis fighters being blown into hamburger by a missile from my cousin's F-22, though.
