The undercover cop is shot and is bleeding profusely and they are waiting for the bleeding cop to somehow move out of the line of fire. I may not know alot about bullet wounds but I know that getting shot in the stomach probably isn't a good thing and the senior cop begins NEGOTIATING after the cop gets shot. Some reason, he stays alive.
The suspect is busy flushing drugs down the toilet. The kid calls the cops. Why not send two swat guys through the window? BAM BAM. Put two shots into the bathroom. Kids stays alive, cop gets saved right away.
Or, what happened to the snipers from the first two episodes?
