U.S. citizens are arrested and convicted for breaking laws in other countries all the time. It's rare that they get out of it because they are a foreigner. It doesn't matter if the laws and punishments are different - whether that be a caning for spitting, a prison sentence for besmirching the king, or even the death penalty for drug dealing. People are obligated to obey local laws, even if they disagree with them, or suffer the consequences.

Not saying there can't be an international uproar, but if laws were broken the local justice system is legally entitled to punish the perp, even a foreigner.

People loose their minds for all kinds of reasons, I can't speak to that ;-)
