Series 10 - Episode 6 Discussion

[Gazelle]

Not sure if anyone's touched on this recently but I still can't understand why Calum and the team didn't do a better job of analysing the CCTV footage that Tariq came across that led to him getting killed. Surely Calum wouldn't have abandoned the analysis the moment he recognised the CIA woman? If he'd followed it through then one of them would surely have recognised Elena which would have avoided all this heartache. Bit of a flaw in the plot if you ask me!
