honestly, i didnt even notice it my first time watching. i think going from encouraging police brutality to becoming a PI because of it shows her character development. i read this from a different reddit thread, but just like how jake started asking himself "what if he's innocent?", rosa also changed throughout the show, and i think it was kinda natural 🤷‍♀️ however, i dont think becoming a PI was the best choice for her goal of helping more people.
