When some nations start harboring criminals of other nations, what is?
Here's the thing. There is something called an extradition treaty, and an international police force called Interpol. If a criminal escapes from India the Indian government can ask interpol to find him/her. After they are located you can ask the government of that country to extradite him for criminal proceedings in your country. Abu Salem was extradited from Portugal to India. In all 60 people have been extradited to India from 19 countries since 2002. Of course you have to have an extradition treaty with that country. Julian Assange has been holed up in the Ecuador embassy, which is Ecuadorian territory, but cannot be extradited because there is no treaty between UK And Ecuador.
