Seriously, what else do you expect ? I mean what in your opinion should be the "reasonable" reaction? Letting them go without even checking the possibilities that there exists any legal option either in Indian or Italian judicial system ?
Apparently you suggest that in order to placate public opinion, excited as it is since one hundred people are in the street denouncing Italy in this same moment in Kollam, arbitrary measures ignorant of international norms should be taken?
Would you be kind enough to post them on this forum if you have access to them ? Are they of the precise moment when the incident happened ?
They will be made public soon as they are already in the hands of our authorities.
You seem to be an expert on what's going on in Indian political scene. Can you point me out which political party is trying to drive mileage out of it ? Its election time across 5 states in India and politicos are throwing up all kinds of rhetoric. Any article pertaining to any party using this issue for political mileage would not be very hard to find.
Just an example BJP as opposed to the current INC in power.

I have come across quite a few Italian consultants in India working on projects. As evident Italy doesn't have the means to support them. I would expect a more moderate and considerate policy than allegedly using lethal force on possibly unarmed fishermen and trying to slip off without immediately alerting the nearest possible coast guard/ naval service.
