“When my son was murdered, that’s a day I’ll never forget for as long as I live,” Carr said. “Enough is enough. I’m going to do my part in trying to save America.”

Her 43-year-old son told police “I can’t breathe” 11 times before he died in New York in 2014, she said. To this day, she has still not seen the full video because it’s painful.

But Sybrina Fulton, mother of Trayvon Martin, said the videos, although unbearable for the family, are a necessary component in sparking change.

Her son, whose 2014 death spurred the Black Lives Matter movement, was killed at age 17 by George Zimmerman, a neighborhood watch coordinator in Florida.

Fulton said to move forward, people need to be aware of what is going on and do what they can to make a positive impact. That involves changing mindsets and teaching kids to not confront authorities at the scene so that they will make it home alive.

Police are not a universal evil, she said.

“We don’t have anything against good, professional, courteous police officers that are there to protect and serve,” Fulton said. “It’s the ones that … kill someone who is unarmed and go home to sleep in their beds.”
