In New York, peaceful protests turned into
confrontations with police. Throughout the weekend, demonstrators clashed with officers in Union Square in Manhattan and outside the Barclays Center in Brooklyn, resulting in injuries and hundreds of arrests.
On May 29, according to court documents, Mr. Mattis had been drinking throughout the day as he exchanged despairing messages over the murder of Mr. Floyd with friends, including Ms. Rahman, who were mobilizing to join a protest. That evening, Ms. Rahman, who was 31 at the time, met Mr. Mattis after he made stops to buy supplies, including gasoline, and joined a swell of protesters in Brooklyn.
Shortly after midnight, with Mr. Mattis at the wheel, according to court filings, they drove in a tan minivan to a police precinct in Clinton Hill. After trying to persuade a bystander to throw a bottle that she was holding, Ms. Rahman got out of the van herself, walked toward an empty police patrol car that had already been damaged by protesters and threw the Molotov cocktail through its broken window before fleeing.
