I’m usually the first to advocate simply avoiding the authorities or outright running from them when it comes to trouble abroad, whether it’s your fault or not. Without a strong grasp of the language and culture –- sometimes not even then -– a foreigner who can’t be understood is more than likely going to be the one thrown in jail, when perpetrators or witnesses can outright lie to the police without you knowing.
However, even when there is a language barrier and cultural differences, there are times when we as human beings –- not travelers -– have a responsibility to act.
