Yesterday, at the "banner bridge" overpass on I-5 near Dupont, activists rallied in support of imprisoned soldier, Kevin Benderman who, according to
The Olympian:

... was deployed to Iraq from March to September 2003. He filed for conscientious objector status in late 2004; his application was denied.

Conscientious objectors are morally opposed to war.

Benderman was to leave for Iraq again in January 2005, but he refused. He was charged with desertion and intentionally missing movement for not boarding the plane for Iraq when his unit left. He was found guilty of the second, lesser charge and sentenced last summer to 15 months in prison. He is serving that sentence at Fort Lewis.

The activists did not have banner bridge to themselves. Apparently there are others who believe that since they have utilized the overpass with frequency they own that particular overpass and it should not be "desecrated".
