Re: Where and When
I know that they can and will, yet they are by international law not allowed to. It is common for countries, especially european countries and the USA to think themselves as the measure of all standarts and to asume rights over other nations, judge other cultures by their own ideals and so on. But being a, supposedly, more moral or more developed nation soes not make it any more right or just. Quite the opposite. Claiming to be on the moral highground, we should even more respect other cultures and other nation's souverantiy and their right to have their own laws. It is acceptable of a fashist dictatorship to discriminate against the validity of other country's laws, that is after all part of what makes them what they are, but not for us.
As you say, travelling on a UK passport gives me certain rights and limitations, yet, if even during travels I am still bound to Brittish national laws, why am I also just as much bound to the laws of the country I am travelling? And when two laws oppose each other, how dare a country claim their law to be superior to the country where the deed happens? Answer, the country within which the deed is done decides if the deed is a criminal act, if it offenses, if damage is caused...or if not. Anything else would be proposterous, asumptous,arogant and exceeing the boundaries of one's authority.
It is just as wrong to demand the rights we have in our own country while being in a country where we would not have such rights. If someone form a country, say... Russia, to stay with that excmaple, travels to UK on a Russian passport, your reasoning would permit that said Russian to commit bribery in Uk. He isn't. WHy not? Because he is Russian and UK law is superior to Russian law? Or is it just a matter of, you get all the restrictions the authorities can possibly think up but non of the rights that come with the territory?
When in Rome do as the Romans.
If you refuse or feel morally or otherwise unable to comply to the cultural or legal precepts of the country you are entering, STAY OUT. If you insist that the country you are visiting or migrating to conforms to accept your culture and laws while you reject theirs, STAY OUT When it is the legal and moral norm in Russia to bribe your way, then when you're in Russia, bribe your way.
If any nation's law takes priority to others, then its the laws of the nation within whom's territory the law is applicable, UK law takes priority over other nation's law only within UK, Russion law is superior to any other nation's law only within Russian borders, American law rules America, etc....for any legal subject of border-crossing matter, we have international law, and this international law states, you can not be done for something that is legal at the time and in the place that you do it.
