Why Rohit Shetty turned down Katrina Kaif's female cop universe offer?

I think with Sooryavanshi doing great at the Box office Katrina Kaif is provoked to play a cop herself. She recently revealed that she asked Rohit Shetty to make a female cop universe movie with her as a lead but he denied and said no to her. She feels that the industry needs strong female cop roles. Do you think Rohit Shetty should make a movie with a female cop?
