'Trigger Point' viewers all think they've spotted the same plot hole - but Vicky McClure is one step ahead

Tense new thriller Trigger Point from Line Of Duty stars Vicky McClure and Jed Mercurio debuted last night - but viewers thought they'd spotted a major flaw to the plot.

ITV's explosive new series which has been executive produced by Line Of Duty creator Mercurio and stars McClure as a Met Police bomb disposal expo, but viewers complained that one part of the series didn't seem true to life - although McClure explained it was actually one of the most authentic details.

McClure's character Lana Washington and her expo partner Nut, played by Adrian Lester, spend episode one tackling a series of bombs rigged up at a London tower block, with disastrous results at the end, but many people watching questioned why they would remove their protective helmets while trying to snip bomb wires.

One person tweeted: "Why would explosive officers take off their PPE?? Surely all the vehicles would have been checked before giving the ok."

Someone else asked: "Trigger Point busy watching … why would the bomb squad keep removing their protective helmets when they are about to be blown up? Surely that would save their life?"

Another viewer wondered: "Who takes their helmet off to diffuse a bomb?"

Someone else commented: "Shoulda worn ur helmet."

But in a previous chat with Yahoo and other press, McClure had explained she had been advised on exactly that point by two real-life expos who worked with the series.

She said: "I think as everybody knows, there are no female expos in the Met. I was speaking to the experts with us, we had two great guys who were on hand every day, there was always something we needed to check.

"It was great having their support so I could ask the silly questions, even so much as 'why have I just taken my helmet off and I'm right next to a device'.

"It made complete sense, everything that they were saying."

McClure clarified about the helmets: "It could actually be distracting, depending on the small space that you might be working in it could impair your vision, and also if it was to knock anything it could be a dangerous thing to do.

"Also the fact that if the explosion did go off, that little helmet is not going to save you.

"It was absolutely fascinating learning these tiny little details, so if there are people who are expos watching, then those moments are in there for them."

After the episode aired on ITV on Sunday, McClure asked fans what they had thought of the final scene where a bomb goes off, appearing to kill Nut (Lester).

She tweeted: "How we doing?! (Even I jumped!!) #TriggerPoint"

Meanwhile, Lester joked: "THE DAY AFTER TOMORROW - Froze to Death RIVIERA- Blown up. DOOMSDAY - Shot in the back with Arrows TRIGGER POINT - Blown up. This job is killing me."

Lester fans shared their disappointment that his character was caught in the blast and hoped to see him return to the series.

One viewer replied: "Brilliant, but Adrian Lester deserved more than one episode!!!"

Another person agreed: "They can't kill off Adrian Lester in the first episode. Not fair!!!"

Someone else commented: "I should have learned after Vigil!!!! I’ve been going round for weeks, describing this as a Vicky McClure and Adrian Lester series. I’ve been totally hoodwinked."

Another fan tweeted: "i screamed!!! (please tell me @AdrianLester is in the next episode though? please????)"

Trigger Point continues on Sundays at 9pm on ITV.
