The storylines on this show are getting less and less believable. The ploy of "good cop/bad cop" is a pretty standard practice so why would an FBI agent feel that was immoral and resist doing that in order to save lives? And when the terrorist was close enough to his target to kill him why would FBI agents merely pull the intended target to the ground and not whisk him away while one of their agents struggles with the shooter? What would have happened if the shooter overpowered him and was now two feet away from his target and armed? The last few episodes have holes big enough to drive a truck through.
