i did cross the border once through Sherpur ( where this man was caught)! We were a picnic party though and it was a bit adventure!! I have also stood in front of a BSF bunker on a hill where shootings happens just to tease your soldiers. Open my profile to see the profile picture, one my friends took the photo from behind while i was standing there!!
The BSF didn't want to do a service to Bangladesh by wasting a bullet. What better way to weaken B'desh, than to let certain people live on there?
If you had kept advancing on into India, then it would have been a different story. So let's credit the BSF with good judgement.
