How and why was she in India to begin with? And if you read the news from around the time this incident happened, her dad said that "He had went back to Bangladesh and came back to India using the same route few times, he didn't think anything would go wrong this time".
I bet if some sort of smuggler crossed over from India into Bangladesh you guys would be complaining that BSF doesn't do its job. BSF job is not to just stop Bangladeshis from trespassing into India but to also stop Indians from crossing into Bangladesh.
And about your little link,my dogs poo has more credibility than that. BSF is not some cult group who enjoys killing people and teenager just for kicks and giggles.
Take off you biased glasses and think for once. BGB needs to do more to stop illegal movement across the borders.
