Agree 100% and I was hacked off that they chose to go this (completely and utterly implausible) route. Not to mention, apart from the testosterone-overload "let's all run around and shout a lot and point guns a lot" laziness, it didn't make any sense at all. Why would bent firearms copper risk it in a crowded police station? Why the shouty (and badly written) convo between Kate and Dot at the end? And why didn't she just try shooting him in the legs first? she's a trained firearms officer and it would have been the right thing to do tactically surely?
argh. it's eating away at me like a case of systemic corruption. It was SO GOOD in parts and then let down by these shenanigans.
