One day after being criticized for not speaking out about the deaths of Alton Sterling and Philando Castile, reality television star Kim Kardashian posted a lengthy note on her website about the Black Lives Matter movement.

“This week we watched Alton Sterling and Philando Castile, two innocent black men, get senselessly murdered by police officers,” Kardashian wrote. “Like a lot of you guys, I watched the videos, and was appalled and completely heartbroken. I was left speechless, angry and numb.”

Kardashian, who is married to rapper Kanye West and has two children with her husband, added that she wants her son and daughter to grow up “knowing that their lives matter.”

“I do not ever want to have to teach my son to be scared of the police, or tell him that he has to watch his back because the people we are told to trust — the people who ‘protect and serve’ — may not be protecting and serving him because of the color of his skin,” she wrote of her son, Saint West.

She continued, “The last thing we need is to fuel anger with more hate or violence, especially toward the many incredible police officers who risk their lives every single day to protect our families and communities. We must peacefully use the power of our voices and the strength of our numbers to demand changes in the judicial system so that brutality doesn’t ever go unpunished.”

Kardashian’s comments came one day after five police officers were murdered by a sniper during a peaceful protest in the city over the deaths of Sterling and Castile. The police deaths were not directly referenced in her post.

“It is our responsibility as Americans and as parents to create a safe future for our children. We must do something NOW,” she added in conclusion. “We must speak up until we are heard and real, effective changes are made,” she wrote. “Alton Sterling, Philando Castile, Trayvon Martin, Mike Brown, Eric Garner, Freddie Gray, Tamir Rice, Sandra Bland, Sean Bell … and unfortunately so many more. Hashtags are not enough. This must end now.”

On Thursday, after Kardashian posted a selfie to Instagram, many commenters criticized her for not speaking out about the Sterling and Castile deaths. Among the stars who have commented on the deaths included John Legend, Jay Z, Beyoncé, Chance the Rapper, Solange Knowles, and many others.
