"As for what redhouse just said, in my opinion, that depends on who ratified the treaty and who didn't. No one but me truly represents me. As long as there are officials left who actively disagree with such a treaty, it's validity is arguable in my opinion. In this case it probably counts though."
As you are on Dutch soil, you are bound by Dutch law whether you agree with it or not. Ratification of treaties is a process that requires multiple, qualified (more than 50%) majorities in both houses of Parliament and all high councils of state are consulted and their opinions weighed; the democratic process toward treaty ratification is extremely rigorous and by all standards can be considered to reflect "the will of the people."
I feel like I can't voice my opinion on the case yet;
First of all, the Netherlands clearly violated the treaty of Vienna (IIRC) that says that a diplomat cannot be arrested, detained or tried in the host country. That treaty - ratified by the Netherlands and hence above Dutch law - supersedes any obligation we have to the diplomat's children (HIS children, not ours). The foreign secretary was right to apologize for the incident.
The second request by the Russian government is that the Netherlands reprimand the police officers who arrested the diplomat. The key issue here is that the diplomat was allegedly drunk and there is substantial evidence that his wife was drunk, as she hit several cars with her car. If he was in fact drunk, it is very well possible that he was not in a mental state to identify himself as a diplomat. I am also curious whether the house of the diplomat concerned is clearly marked as a diplomat's residence and whether the diplomat's wife's car who hit the other car has CD (Corps Diplomatique) identification and if it did, if that information was known with the police and if it was, if that information was transferred to the police officers who arrested the diplomat, because in that case they should have been very sensible to the question of whether a member of the Diplomatic Corps was involved in the alleged crime and the initiative to identify the diplomat as such would have resided with the police officers.
If, however, the house of the diplomat is not marked as a diplomatic residence, the police officers who detained the diplomat were not aware of the car incident that happened around the same time and the diplomat was not in a mental state to identify himself correctly - in other words, if there was no serious reason for the police to suspect diplomatic status - then no other conclusion remains then that the police acted correctly. But as a diplomat was detained regardless his ability to identify himself, the government's apologies should stand in any event.
