German riot police are a sight to behold — well-trained, organized, effective, and nobody screams “my civil rights were violated” after they’re done (or, at least nobody listens to them).
They must train at the same place as their passport "police." I was very tempted to set off an international incident when a passport official in Frankfurt screwed up his face into a terrible scowl when he saw my U.S. passport, then literally threw it back at me. He did the same with every American in line. The Germans hate us but not single one threw my money back at me when I did business with them.
