The German authorities made some fundamental faults in the very beginning of this summit. They wasted 100.000.000,- Euros (this is NO bad joke) of hard working German taxpayers on "soft security" like a 12 km long fence and a few thousand policemen for a meeting of 8 gentlemen. If 100.000 protesters should appear on the scene it will make 1000,-Euro/protester for security. I have to say that most of those 100.000 are neither agressive and/or terrorists. That leaves 5000 to 10.000 idiots we have a real problem with.
Therefore I believe that a no go area and a few cheap MG stands would have done perfectly.
I am extremely angy about my tax money being wasted for that kind of BS.
