Yes, but getting arrested requires "dringenden Tatverdacht" (strong suspicion) here. An IP address isn't sufficient without any additional evidence.

(Disclaimer: I'm not a lawyer, exceptions apply)

For future reference, there is no legal requirement that says you need to formally announce you're not a lawyer on internet forums.

It can still be useful to do so thought, as a shorthand for there potentially being nuances or exceptions to the claim you are making of which you are unaware.

Making a statement just to avoid an edge case is what we hackers like to call "boilerplate". We don't find it useful, and generally prefer to avoid it, both for the writer and the reader.

I think it pretty important. The logic goes like this.

"This person seems really knowledgeable on law" which leads to

"Must be some sort of a lawyer"

They then go on to assume they have gained valid legal knowledge.
