Did they just cross the line on 9/11?

I ask this as a serious question. I have not seen the video that Olbermann references -- I've been watching football, but I've got the video recorded and I'm going to watch it now.

I hope Keith is wrong.

Update (6:35PM): The Boston Globe chimes in. "One of the most enduring taboos in American politics, the airing of graphic images from the September 11 attacks in a partisan context, died today. It was nearly seven years old."

Update 2 (6:49PM): You can watch the "tribute" video here. It's definitely a partisan video -- without actually naming McCain, it expressly advocates for his election, saying that we will win the war on terrorism because "we will have a president who knows how." My verdict: way across the line. It shows the explosion of the second plane, the collapse of one of the towers, and the blood of the dead.
