Forget China... Is Google Censoring Information Right Here in the US?

Seems everywhere I turn I can't help but notice that Google's business decision to collaborate with the Chinese government to censor Internet content has been widely frowned upon. So it's with great trepidation that I read about possible censorship of content by Google right here in the US (thanks to Stephen Mansour for passing this info along):

News stories have reported Google’s decision to censor content within China. But is Google also censoring content in the USA? Searching for "big boom" on Google’s own video search service returns a listing for this video of an IED explosion. The description is as follows:

17 sec - Oct 25, 2004
"Detonation of Improvised Explosive Device used against Coalition forces. We found this one before they could use it against us."

 Instead of a video playing, a message appears, stating:

"This video is not playable in your country."

In your country? My country is the United States of America! This is a standard Cox Communications cable connection located in Virginia, USA. Checks with several friends indicate that this "not available" message is showing up in the United States, but friends in Canada and South America are able to view the video. Military operations are certainly a point of controversy right now, but I would expect Google to present all available information within our democratic borders. Is Google censoring information in the United States? 

Update: There are several of these censored videos.
