@freemo Yeah sounds wise as all job types might try it on in some way.
Often proving those in power are in the wrong after the fact is problematic so maybe filming them and yourself giving them the trespass 'order' *might* help... though suggesting to film others is maybe not the first things but something I'm trying to solve theoretically as usually wouldn't
but when officer's opinion of what happened are believed more than civilian's in court (again another tactic in them trying force their way in or being too nosey) it's hard to prove things and was thinking in the same way 'how to solve if they said this happened or put their foot in the door etc'.
How to solve that?
