After the horrible case of the man who was assaulted in the supermarket because a thug questioned his right to be parked there and who subsequently died?
I was listening to the story following the court case and maybe public information films would hammer home the message that :-
sometimes the passenger can be the disabled person.
Or the disabled person might still be in the shop.
Or the disability might not be obvious.
And that blue badge holder can park in P&C spaces.
Would public broadcasting information films help?
