What most Indian members are saying is simply this (I put it in bullet points for ease of understanding)
*Two innocent fishermen were shot dead.
*The Italian guards on the merchant vessel are the main suspects in this unfortunate incident.
*In case the Italians did the shooting it was likely an over-reaction or maybe an accidental shooting.
*The Italians are under court custody and the case in under investigation.
*In India investigations and court procedures take longer than in most Western countries, so people have to be patient.
*Justice will prevail in the end.
Now please tell me which part is cave nationalistic as you point out ?
