I had that kind of argument with a teacher once... she tried to tell us that there were no reporters who would go and mingle with the troops before Iraq (this is a GT world history teacher with a degree). I told her she was blatantly incorrect. I had a copy of Black Hawk Down in my backpack, so I flipped to the photos and showed her the only pic from the ground battle. She stood me up in front of the class, put her arms around me, and said... "honey.... YOU'RE WRONG! Now go sit down."
