Entrapment????

I wonder why is CNB entraping small timers when we don't even know if he is an active trafficker(at least I don't have the information). Instead of surfing the net for prey to toy around, maybe they should really spend more time hunting down the real drug baron. I hope CNB is not patting themselves on the back for a brillantly executed plan. I think they caught a scape goat who bought the drugs from the real trafficker. Don't we watch enough TV drama to know this? I hope Adrian Yeo would be able to move on in life after this episode.
