You are mixing a lot of things here. For one, taking a picture of a crime happening as capturing evidence overrules the right to one’s own image, as does the freedom of the press when capturing images of events of public interest.
However what is not okay, and I find that pretty reasonable, is taking a picture of someone else unaware of having their picture taken. I don’t want somebody taking a picture of me going about my life, no matter if I look goofy or wear an extremely cool outfit. You don’t get to take a picture of me, and I won’t take one of you either.
That does absolutely not imply that you couldn’t capture scenes of importance for whatever reason, and that happens literally all the time.
Germany sits on the 14th position of the press freedom index - the narrative you’re trying to construct about some kind of repression on documenting events in the public sphere is just not true.
