Correct or not?
I read the following piece of information in a book written by a non-native speaker of English, but I am not sure whether it is correct or not,
The writer of the book says : We use mustn't have + pp. to express prohibition or when we regret doing something illegal in the past. We also use it when we blame someone for doing something in the past.
Examples
- I mustn't have smoked in a petrol station.
- You mustn't have parked here. It is a private park.

Omar Ahmed - I mustn't have smoked in a petrol station. I would take that to mean that you have new evidence that rules out your having smoked in a petrol station. Omar Ahmed - You mustn't have parked here.
