Escalation during an official act: clarify the precise sequence of events before questioning.
Resisting state authority under § 269 StGB requires that an authority or an official is obstructed in an official act, or coerced into one, by force or by a dangerous threat. Merely passive conduct or verbal protest does not readily fulfil the offence. From a legal perspective, the precise sequence of events is decisive.
Do not make a statement on the matter before you have obtained access to the file and sought advice. Record what actually happened, what words were spoken and whether there are witnesses or recordings.
