The Chaos Computer Club (of which i am a proud, albeit currently rather inactive member) and a Dutch initiative Wij vertrouwen stemcomputers niet (literally "We don't trust voting computers") has proven, that electronic voting machines used in Germany  and the Netherlands are inherently unsafe and urges the government to abolish their usage, as they respectively any electronic voting devices ultimately pose an unnecessary threat to the democratic process. Details (in German) can be found here.

Now there is an official online-petition at the Deutsche Bundestag supporting this motion, which I would ask you to consider signing.

N.B.: The link points to a webserver located at Napier University, Edinburgh which carries out the petition, so don't wonder about the weird URL (the official explanation for that can be found at the website of the Deutsche Bundestag.)

Also noteworthy: the strongest voices against the use of computers in voting seem to come from online- and hacker-communities, while the only defenders seem to be the manufacturers (the linked 'news item' is really just a slap in the face of any concerned citizen, Mr. Groenendaal ought to be ashamed!) or clueless municipal employees. I think, that says something...
