You simply can’t answer what law was broken by the dentist. Instead you are using the “law” argument to promote your animal rights perspective.
I do not know the laws in Zimbabwe and I doubt you do either. However, IF what he did was illegal in Zimbabwe do you think he should have gone there and broken their laws?
I am not making an animal rights argument at all.
If chewing gum is illegal in a country then you should not travel there and chew gum.
The logic being displayed here is that countries are not sovereign and do not have a right to make their own laws.
If people can go to other countries and break their laws then why can’t people come here and break our laws? Are we sovereign nations or just One World?
