Many years ago, after I got a bit bolshy, (18 years old, I knew everything...) I refused to move on when busking with a mate in Sheffield. (Ok, England not Scotland but the law for both seems grey.)

In the end I was marched off to the police station where the desk sergeant told me I was being cautioned for "aggressive vagrancy."

Many years later, when I needed an enhanced CRB, it didn't show. I have had CRB checks at regular intervals since and still, never turns up.

Can't help thinking plod was bullshitting me in order to get me to stop busking, (the aim of their exercise I suppose,) and there is no such charge, or if there is, I couldn't be charged with it.
