It is somehow interesting that I have taken the pictures for this weeks PABUCA topic at a quite peaceful politic demonstration.
An armored Police truck in standby to clear road barriers (if there were any).
Actual Police-built road barriers (only genuine with barb wire on top) to protect the European Central Bank.
They even locked down the tram line. Seriously felt like a warzone (at least as close as you can get to one in downtown Frankfurt).
