The US military in Iraq announces it is clamping down on individual soldier blogs for security reasons on the same day it began advertising that it's public affairs division has started using Youtube to give the folks at home an "unfiltered perspective" on events in Iraq.  Officially "unfiltered" means showing anything that "does not compromise the security of its troops and operations, violate laws or include excessively gory, disturbing or offensive material", ie. anything that might make it abundantly clear how horrible war is.
