In the hours after the rioting. Henry Raymond, the city's finance director, approved the purchase of thousands of pieces of equipment.
"Approved," Raymond wrote in an email with a 4:01 a.m. April 28 timestamp. His email was in response to a request for 1,000 pairs of "protective riot gloves," 1,000 pieces of chest, leg and arm protection items, 1,000 riot shields and 1,000 baton rings, among other items.
Gray's death from injuries obtained while in police custody sparked days of mass demonstrations in Baltimore.
Before the protests turned violent, one member of the police department emailed fellow officers as he looked for his riot helmet.
"Missing riot helmet," Phillip Tabron wrote in the subject line of an email sent at 11:19 a.m. April 24.
"Did anyone in the Northern District remove my riot helmet from my locker if so please return. Thanks," Tabron wrote.
