Our DGFI guy who is responsible for checking on people's conversations and monitoring anti state activity is a lt. colonel who had jt. black ops traning from the US, its just the guys on the street are not good at their job, they will have to make everyone understand that they are dgfi. For example when i go to kurmitola golf club you could tell the guys are dgfi by their crisp shirt and the way they look at you when you are driving with loud music on, another example would be 2 dgfi guys sitting on a bike, one behind holding his phone and talking loud, you could tell the guy is dgfi. Moeen U Ahmed used to walk at the golf club road, you would see 2 undercover guys walk behind him...it was so obvious they were dgfi that its not even funny.
A BNP uncle of mine has 24 hours dgfi surveillance on him. There is this guy dressed as this beggar sitting down in front of his house wearing sunglasses all the time. Sometimes he'd show up if he goes shopping and all. So yeah, its not that our dgfi is useless, it works for the government instead for the nation, just like our police force.
its a beautiful song, but in lala land. National security is our main concern. Right now Bangladesh is in the risk of losing her sovereignty.
