It’s time for revolution now, or it’s time for demonstration. The right to demonstrate is a fundamental right in Germany, and this is great. A demonstration is a good way for a group of people to show their opinion.
Demonstrations can be different, like a rally, a march, or a sit-down-strike. They can be big or small, loud or quiet, they can be against something (like a new law), or they can be to support something, like freedom.
The first photo shows a protest march by Kurds in Cologne about three years ago, against the suppression of Kurds by the Turkish government, and the second photo shows a march in Munich this week, against a new bill, called "Polizeiaufgabengesetz" ("police duty bill"), proposed by the ultra-conservative government of Bavaria, which will lead to severe restrictions in personal freedom of Bavaria's citizens in Munich this week.
