Members of the Catholic Workers have a history of actions at military installations. For example, read this account of the actions of Peter DeMott, one of the four convicted of spraying blood at the recruitment center:
"On December 13, 1980 Peter DeMott, former seminarian and Vietnam veteran from Jonah House, entered the General Dynamics Electric Boat (EB) shipyard in Groton, Connecticut during the launch ceremony for the "USS Baltimore" fast attack submarine. Noticing an empty EB security van with keys in it, he got into the van and repeatedly rammed the Trident "USS Florida" denting the rudder. Security guards then broke into the van and arrested him. He was tried by a jury in New London Superior Court and convicted of criminal mischief and criminal trespass. He was sentenced to one year in jail."

Did you (or anyone else) catch the segment about the US Soldier who returned home from Iraq for Christmas and was killed while walking his wife in the park in Raleigh NC? That story made me furious. I looked for a thread concerning this but couldn't find it.
