Off-topic question: India does not accept dual citizenship. So when the Kosuris became naturalized citizens, they must have given up their India citizenship. Given that, why should India accept them back after they were deemed criminals in their adopted country? What is the legality around revoking naturalized US citizenship? Usually the way this works is that country A doesn't "recognise" dual-citizenship, which means if you are a citizen of country A and country B and you commit an offence in country A you don't get to say "well I am a citizen of country B so that doesn't apply to me". I am not sure if India requires you to give up your citizenship on taking another, but if they did it would make sense, and in fact it's surprising that that doesn't always happen. If a citizen of country A wants to become a citizen of country B instead fair enough but it's not in the interests of A or B that they should retain citizenship of A too.
