Having already been cancelled twice, CBS' hit series S.W.A.T. now faces a further third cancellation following the upcoming May finale of its eighth season. This time, said cancellation seems more final than before, with S.W.A.T. fans desperately hoping their favorite procedural won't actually be laid to rest for good. Before any sort of permanent resolution may be decided, there's the small matter of a two-part, two-hour special finale that will see Shemar Moore and the rest of the Twenty Squad face their toughest challenge yet, certainly if the promo for the finale is anything to go by.
