1.5 Million [15 lakhs] Indians are living in US. Even though the death of the student is very unfortunate and action must be taken immediately, we should not exaggerate it as a growing insecurity.
Imagine a city in India with 1.5 million people. Everyday at least 10 people die of murders and suicides and another 30 die in accidents. Comparatives, Indians in US are still safe so far!!!
Even in ragging incidents in India more students die every year.
