After Killing Bala, it was odd that Hafiz just leaves the body lying there and goes to participate in marriage celebration as if nothing has happened. He had enough manpower, he could have assigned a few men to dispose of the body, or some way to keep a watch on it so that he can see right then who if at all approaches the body, so he didn't have to rely on cctv camera footage later on, wasting time. Then there was a huge commotion when the team takes away the body of Bala in the name of medical emergency, so a person of the stature of Hafiz should have enough security in place to inform him of such medical emergency as it might pose danger to him and his guests at wedding. All the time it took for the team to take body out was enough for Hafiz to play his card and capture the team then and there. It seems that the script writer/ director were hell bent on following the sacred tradition of bringing the body of Bala back to home, so they created all this illogical scenario so that the team gets hold of the body and extracts it.
