I know about the G11 and the 4.73mm caseless round, you realize these aren't the rounds involved, and do you realize how rare it is someone has a 4.73 or even be able to purchase because that particular caliber and round is relatively rare. The fact is those "rounds" were in his suitcase in his jacket pocket, no gun either in his suit case or his person to even fire those rounds, and if those few rounds really were caseless then those aren't live rounds, no potential to fire, no situational potential to fire, nothing period.
The truth is India is simply looking for opportunity for revenge against a US citizen happening to be a NYPD officer after US marshals had their way with an Indian diplomat in NYC, it's not about those few round parts he had in a checked suitcase.
