The word “regime” most closely means as it is used in paragraph 9 as a way of doing things that is imposed by those in power
Explanation:
The line that includes the word "regime", "The New York Civil Liberties Union (NYCLU), protested that “[n]o research has ever proven the effectiveness of New York City’s stop-and-frisk regime" implies that it is something that affects the way citizens used to do thing, and it also says that it is applied in New York which makes it something totally governmental.
