There, fixed it for you.
Police in Europe (at least in Germany and here in Austria) are allowed to raid your house when they believe there is imminent danger to the security of the state or other citizens ("Gefahr im Verzug"). They don't need a judge's permission/order for this. If they don't find anything, they can just file a simple 2 page report and be done with it.
This was used in the case of wikileaks.de - the police didn't read his rights to Mr. Reppe and when he insisted the police add a witness name to the report, they didn't do so.
Actually, they did have the permission of a judge, at least according to this: http://www.heise.de/newsticker/Hausdurchsuchung-bei-Inhaber-der-Domain-wikileaks-de-Update--/meldung/135147
Although you are right that police can enter the domain without judges under certain circumstances, evidence might be forfeit if they did it for the wrong reasons. It is not as easy as you depict it, even if it would apply to our case here (which it does not).
I too think that the German police has too much power (especially warrants like these are a bit fishy at times, not to mention copyrights, demonstration rights, etc), but we are still a democratic state with a halfway decent judicial system.
