That was my first suspicion too but they keep calling him a scaffolder. How many 22 year old scaffolders get granted firearm's licences? The weapon is supposed to be a pump-actions shotgun. I know some pretty tasty people (tangentially) that I could probably get a weapon from but a pump-action shotty would be a major ask. Something is a bit hinky about the whole thing.
Youtube has helpfully deleted his account for failing their "code of offline behaviour"; I wonder how far down the code the "no murder/suicide" clause came?
