You are a surgeon from the US who decides to lend his/her services to help the people of Australia, who were victims of a huge tidal wave.
You are flown to Sydney, Australia to help out the victims of the biggest tidal wave in history. The city was all but destroyed, and hospitals around the country are packed with crying, bleeding victims. Your help is greatly appreciated since you are one of the best doctors in the US, where you specialize in chest injuries. When you arrive, you are immediately put to work setting bones, sewing up torn limbs, and treating victims for shock. Among the victims you find one man who has suffered severe injuries to his lungs from submersion; his lungs are partially collapsed, and he is in severe pain. You remember a similar case back in the US where a man who went through a similar trauma fully recovered after undergoing a new procedure pioneered by an old med-school friend of yours. Knowing how important the process could be to other doctors, your friend posted the process on his web site in the US.
You find a computer and try to get the information from his web site. For some reason the signal is being jammed by the government. After explaining your situation to the authorities they realize that the case of medical emergencies is one of the conditions that was discussed in the treaty they have with the United States. They allow you to receive the information and apologize for causing you any inconvenience. As a result you are able to save the man's life using the procedure your friend invented and posted on a web page.
