One day after the broadcast of an interview with the officer who killed their teenage son, Lesley McSpadden and Michael Brown, Sr. appeared on the "Today" show to respond. Describing the last 36 hours as “sleepless” and “heartbreaking,” the parents of police-shooting victim Michael Brown questioned the believability of Darren Wilson’s account and lamented a Ferguson grand jury decision not to indict the officer.

“It’s like insult after injury,” McSpadden said in response to Wilson’s contention that 18-year-old Brown “looked like a demon” and that he felt dwarfed by the teenager, who was the same height as the officer. “So disrespectful.”

Brown’s parents were joined by their lawyer, Benjamin Crump, who said they will continue to pursue legal avenues to seek justice for their son’s murder. In a public statement, they urged supporters to “not just make noise—let's make a difference.”

Crump also advocated for the passage of the Mike Brown Law, which would require every police officer to wear video body cameras while on duty.
