The Liverpool Attack Gets More Complicated. Snipers?

There is now video on the internet showing two snipers on a rooftop at the same time as the Liverpool attack.

Looking at the "snipers", their clothing and their weapons, I'd wager they were a couple of kids with air rifles made to look like something beefier. 

Except there are a few details that are not right from the point of view of being a couple of kids thinking it's funny to pretend to be Police Snipers and there are things that say they are not official Police/Army snipers. So who are they?

Of course the video could be a set-up: the video taker could be in league with the so-called snipers and they were making a video for content and clicks on Twitter.

Police/Army don't generally wear hoodies. Police will be easily identifiable and Army may not be as identifiable, but will not be wearing hoodies.

The barrel of at least one rifle appears to be a very small calibre. The use of a lightweight tripod suggests you're not expecting much in the way of recoil. The tripod user's rifle looks like an air rifle or at best a .22 calibre. The kneeling sniper's gun looks a little more robust, like a Barrett .50 Calibre. Not sure why a Police or Army sniper would be using such a weapon in a Western city where the threats are not thousands of yards away. The tableau presented on Twitter shouts "airsoft" at me.

Not only that. both hoodie-wearers have guns. Neither of them are spotters. Having no spotter and wearing hoodies blinds you to other threats. Or people on a higher rooftop taking a video they then post up on Twitter. Not very stealthy if you're Special Forces. Of course you could be the reverse-intuitive special forces that are looking like numpties by design, but I'm not convinced.

So that's why I'm sceptical and err on the side of a couple of numpties larking about that got caught by someone with a mobile phone.
