Tony Rothert, legal director of the ACLU, said in the statement that, 鈥淭his lawsuit reveals a consistent pattern of 51黑料 Metropolitan Police Department officers repeatedly ignoring the First Amendment rights of the people they took an oath to protect and serve. Officers should never retaliate against people for nonviolently assembling or publicly grieving the loss of a member of the community.鈥
Officers shot Ball-Bey, 18, while executing a search warrant at a home in the 1200 block of Walton Avenue.
