The President In Mainz

Roger Boyes of the Times seems disappointed that German anti-American protesters won't be able to rip President Bush to pieces during his visit to Mainz. He details security measures and how inconvenient that are to people while at the same time describing how anger has united all the "tribes" in Germany for a "huge, swelling protest" in Mainz.
Ten minutes down the road from Mainz is Russelheim. Security is having the Opel factory there shut down for the visit, and the spokesman is complaining of lost output. I don't know if the Opel factory was shut down on August 26, 1944, when six American airmen were executed there after first being marched through the gauntlet where the locals beat them senseless.
Evidently, despite the request of President Bush to have a walking tour and a town meeting, German authorities are keeping things tight. Maybe they have a reason for doing this.
Maybe it's less about the policies of the President than it is about the vicious character of the local mob.
