Kurzbesuch in Berlin

As you might already know: there is the G8 summit in Heiligendamm taking place, which is near Rostock – the place where I live.
Although there were some street fights between violent opponents (hiding in the mass of other demonstrants) and the Police, it’s been quite silent so far. The summit begins today and apparently the demos and actions against the summit are starting as well.
When driving around (work/home) you can see Police everyone: at the train station, on bigger crossroads, on bridges, under bridges, driving around, etc…
It’s like you’re living in a police state.
