Are you based in Scotland and practice Scots Law?
Before I was allowed to leave the policeman asked if I had anything to say if i did so this could be used in court as evidence against me. "Did I want to reply?" I said no and was asked to sign his notebook. By doing so have have I done the right or wrong thing? would this be seen as unhelpful or obstructive? I was like a rabbit in the headlights and didnt want to make matters any worse by saying the wrong thing.
