There’s any number of reasons why the officer didn’t fire, anything from not having a clear background for over penetration or a miss, to information being passed that it was likely a replica firearm. But that said, from that picture I think he would be totally justified in taking the shot. Although whether the IOPC, press, social media and 5 to 10 years of inquests and court cases would think the same is another matter. Massive credit to the officer though for the bravery and restraint shown.
Stuff like this shows the stupidity of the laws around replica firearms in this country. You have to prove a defence in order to buy a black or realistic coloured airsoft gun, but you can walk into any outdoor activity shop and buy a black pellet gun which looks exactly the same. I can just imagine the comments from people seeing this wanting anything that looks like a gun banned, regardless of the fact that the only person who’s life was at risk in this situation was the idiot with the BB gun. As far as I’m concerned you should be able to buy what ever replica you want and if you’re stupid enough to act like this idiot with it, then so be it. Let Darwin sort everyone out.
