In Schengen, you might have to have your identity determined by the police at the police station, so yeah, you can be detained for that.

Searches, in Germany, generally demand cause. I have no idea what laws govern searches in Switzerland.

The part with citizens vs non-citizens was mainly about borders. The US is known to be incredibly mean to non-citizens, going so far as to require a visum for transit, whereas Schengen only requires a transit visum for citizens of a small number of states.

It seems strange that Swiss police did a random search. Anyway, it seems that the US police also does random searches—at train stations for example.

Schengen only requires a transit visum for citizens of a small number of states.

Schengen requires a transit visa for citizens of 140 countries. There's only about 40 countries that don't need transit visas. The USA has visa waiver programs with more than 36 countries, and other similar arrangements with Canada, Mexico and states in the Caribbean.

No, the police in the US cannot randomly search you in a train station. The only circumstance in which you can be searched without probable cause without consent in the US is by border security.

It seems that the US police would like to search you at as many locations as possible. In many cases this is not legally possible. However, the German police does not seem to have that attitude, or at least not that extreme. (Remember you are talking to an 18 year old who is not a lawyer.)

It is very apparent that I'm talking to someone who doesn't understand how the law works in the US. I don't hold that against you (why would I? I don't know how it works in Germany!), but I recommend that you develop fewer strong opinions about how things work here until you read a book or two about it.
