The propoganda is not because Dr. Loganathan got killed in US, it is because of the way he was killed/faced death. What would you and I know about the pains he must have gone through to get to one of the prestigious universities in the world? He is a man who has chased his dreams and lived up to them. Remember he died as a teacher while teaching.
I may not have known Dr. Loganathan personally but being a Civil Engineering Graduate I know the contributions he has done not just to India but to the rest of the world. FYI he is one of the world's pioneering Hydrology expert. Today even the American Society of Civil Engineers has paid tribute to Dr. Loganathan and it is unfortunate that people of his own country did not recognize his efforts and above that they criticize his death. Yes, that is indeed a shameful act on part of you and everyone who supports you.
Shastryji and all Kargil heroes are always remembered.
