How does one "leak" 90,000 military reports?

It seems as though nothing short of what appears to me to be a sad lapse in security will get our troops out of Iraq and Afghanistan.

This story (clipped directly from the lead-in paragraphs of both CNN;s and Google's #1 news item today) should give all of us a creepy feeling:

"A whistle-blower website, WikiLeaks.org, has published what it says are more than 90,000 United States military and diplomatic reports about Afghanistan filed between 2004 and January of this year.

The first-hand accounts are the military's own raw data on the war, including numbers killed, casualties, threat reports and the like, according to Julian Assange, the founder of WikiLeaks.org, which published the material Sunday."

According to Assange, the leaks amount to a "total history of the Afghan war from 2004 to 2010, with some important exceptions -- U.S. Special Forces, CIA activity and most of the activity of other non-U.S. groups."

I really want us out of there, but surely our military should keep closer wraps on its reports. I hope they are not Top Secret or so sensitive as to endanger our forces who, for good, bad, necessary or otherwise, are over there fighting.

This "leak" looks awfully suspicious to me ...
