Sorry but .......

How the fuck did he get to the police station... ???

More so, he pitches up with the gun while sitting in front of the officer.

Surely the common sense approach is to ring 999 or if you dont consider it an emergency the local plod who would more than likely send an Armed Response Vehicle.

Leave it at the bottom of the garden but keep an eye on it to make sure no one comes back for it, or at the least move it somewhere safer.

Taking it down to see the local super is frankly bonkers.
