It was a pen, but did you read this part?
"And it’s a bit depressing that this country is now willing to accept blatant flouting of debate rules, because it was “only a pen.” Kerry was specifically forbidden to do this, by rules to which he agreed after much negotiation—but he did it anyway, apparently without even thinking."
He still cheated....
Like to see the pen. The reason they had writing implements provided was so nobody could use a "rigged" pen. I'm not saying that it was rigged, just saying it's possible. Easy enough to have a small single line liquid crystal display that shows text that is received by the pen. Again, not saying that is what it was, but the point of the agreement about not bringing your own pen is to eliminate doubt.
I wouldn;t trust kerry as far as I could throw him.
You know that is a fake photo don't you. It's NOT a pen. Notice they dont' have it frame by frame on the site you quote...they picked a later picture and stuck it next to the other pictures....Don't be fooled.
