Involve the police?

Many years ago I had an issue at Birmingham Market when the security wouldn’t allow me to stay and I refused to leave because my hours were up. I called the police for advice and they sent down 2 officers,one very much a junior and the other a flat hat.
This was about 0500 and they escorted me to a street about a mile or 2 away with double yellow lines for miles. They told me to park there and I would have no problems. I had 9 hours or whatever sleep undisturbed.
Would that work nowadays to transfer responsibility away from the driver onto the authorities,do you think/
